About the MTCT300

MultiTech CT300 (MTCT300) is a wireless and self-powered electrical current monitoring device. It is capable of reporting average, peak, and minimum RMS Amperes and tracking accumulated Amp-Hours. The device parasitically harvests energy from the monitored conductor, negating the need for routine maintenance to replace or charge batteries.

MTCT300 uses sub-gigahertz LoRaWAN for long range wireless communications. This IoT interface can be deployed as a private network, or used with an available public one. The use of short data messages increases reliability of transmission in suboptimal environments such as metal electrical panels.

Device Overview



Scoping

Circuit

Determine the circuit(s) where the MTCT300(s) will be installed.

Note: Count the conductors to determine if the circuit is a two-wire single phase (one Current Transformer), three-wire single phase (two Current Transformers) or, three or four-wire three phase circuit (three Current Transformers) to determine the number of Current Transformers required.
Note: MultiTech recommends MTCT300 on each hot conductor.

One-Line Electrical Drawing

MultiTech will provide scoping of Current Transformers for our customers. To do this, MultiTech requires one-line electrical drawings and pictures of the conductors. If possible, the pictures need to show the conductor size and insulation type.

Electrical wires are labeled with standardized markings that provide critical information about their construction and intended application. These markings typically include the wire type, voltage rating, wire gauge, and the conductor material. This labeling ensures proper selection, code compliance, and safe installation across a wide range of electrical applications.



 Please provide MultiTech with the following information for proper device selection.
Conductor Size: ______________
Insulation Max Voltage Rating: ______________
Cable Type and Application: ______________
Conductor Type: ______________
Certification: ______________

The correct Current Transformer for the given conductor(s) can be determined once the conductor size that the Current Transformer will be installed on is determined. The appropriate Current Transformer can be identified once the conductor size is determined. Using the conductor(s) size and the table in Common Conductor Specifications, select the appropriately sized Current Transformer.

Conductor Sizing

The outer diameter of an electrical wire is influenced by several key factors, each directly related to the markings and specifications found on the wire:

  • Wire Gauge (AWG or kcmil) – The larger the wire size, the thicker the cable. For example, a 10 AWG wire has a significantly smaller conductor cross-section than a 4/0 wire or 500 kcmil cable. As the conductor size increases, more material is needed, which directly increases the outer diameter.
  • Conductor Material (Copper vs. Aluminum) – Aluminum has lower conductivity than copper, so a larger diameter conductor is required to carry the same current. This means aluminum conductors generally result in cables with larger outer diameters than their copper counterparts at the same current rating.
  • Insulation Type (e.g., THHN, XHHW, RHW) – Different insulation materials have different thickness requirements and thermal properties. For instance, XHHW insulation is typically thicker than THHN, resulting in a larger outer diameter even for the same gauge and conductor material.
  • Voltage Rating – Higher voltage ratings often require thicker insulation layers to maintain dielectric strength and prevent breakdown. A 1,000V-rated cable will generally have a larger outer diameter than a 600V-rated cable of the same gauge and type.
  • Wire Construction (Solid vs. Stranded) – Stranded conductors consist of many small wires twisted together and require more space and insulation than a solid conductor. This adds to the cable’s overall diameter, especially in flexible or high-strand-count designs.

In situations where a conductor’s type, gauge and other ratings cannot be directly determined. It may be nessesary to measure the outer diameter using a non-conductive tool or upsize the MTCT300 to ensure proper fit.

Common Conductor Specifications

The following chart is based off of 600V THHN/THWN PVC insulation with a Nylon outer jacket per UL standard 83. These values are minimums permitted and may not be characteristic of all cable manufacturers. Nylon jacketing is assumed to be 0.005" (5 mils) and included in the insulation thickness.

Ampacity ratings are per the 2023 NEC Table 310.16 with an ambient temperature of 30°C.

Applicable Circuit Types

Determine the circuit type to identify how many devices are needed. Install one MTCT300 per phase; the neutral typically does not carry full load current in multiphase systems and should not be monitored. See Wiring Color Codes for additional details into identifying a circuit’s type.

For high-current systems with multiple conductors per phase, a single MTCT300 must encompass all conductors in a phase to accurately monitor the current.

Load Suitability

MTCT300 is a self-powered device that parasitically harvests energy from the monitored circuit to operate. This gives the MTCT300 the advantage of requiring no external power supply or regular battery changes. However, harvesting from the source imposes a few requirements on the monitored circuit.

  • The MTCT300 requires current to be flowing in the monitored circuit in order to harvest energy.
  • There is an initial charging time before the MTCT300 has enough energy to begin operation.
  • The amount of current flow in the monitored circuit determines how long the MTCT300 needs to charge before operation and what operational state it can maintain.

The MTCT300 has multiple low-power modes to enable circuit monitoring before high-power systems such as the LoRaWAN radio are enabled. These extend the operational range of the device across situations such as low circuit currents or momentary shutoff.

Warning:

MTCT300 is not suitable for all loads and circuits. The device will perform poorly under the following conditions:

  • Loads with less than 1% of the rated sensor current.
    • Very low currents impact the accuracy of the current transformer, and may not provide sufficient power harvesting for the MTCT300 to operate reliably.
  • Loads that are active for short periods of time.
    • Due to the initial charging time, the MTCT300 may not reach operational state before the load shuts off.
  • Periodic loads where high-accuracy amp-hour totalization is required.
    • Current flowing in the circuit while the MTCT300 is initially charging is not recorded. Loads with many on/off cycles may not give high-accuracy amp-hour totalization.
    • MTCT300 continues operating for some time after the load has shut off. Periodic loads where the off-time is shorter than the MTCT300’s power-off discharge will not be impacted by repeated initial charge states.

Non-ideal conditions can be mitigated by externally powering the MTCT300 with a 5V micro USB power supply.

Before Installation

MTCT300 Latch

The MTCT300 uses a split-core current transformer to allow easy installation on existing wiring.

  • To open the MTCT300, gently pry the front latch outward by a few millimeters and rotate the hinged transformer half upward.
  • To close the MTCT300, rotate the hinged half downward until the latch clicks into place.

Exercise caution when handling devices exposed longterm to heat and high humidity. These conditions can eventually cause the nylon plastic to become brittle, increasing the risk of latch or hinge breakage if forced.

Installation Location

Warning:
  • Note the MTCT300 can only monitor a single AC phase. Combining phases within a current transformer will result in inaccurate readings due to phase offset.
  • Failing to encompass all conductors in a phase will result in inaccurate readings.
  • Generally the neutral conductor does not carry full load current in multiphase systems and should not be monitored.

The MTCT300 is designed to hang from the monitored conductors. If installation on a vertical conductor is necessary, non-conductive cable ties or similar are recommended to hold the MTCT300 in place.

For maximum wireless reception the LoRaWAN antenna should be angled away from metal sidewalls as much as possible while not being perpendicular to the antennas on the LoRaWAN gateway.

It is recommended that a minimum of 1" (25mm) of clearance is maintained between current transformer devices such as the MTCT300. Placing multiple current transformers adjacent to each other will impact their accuracy.

Installation

Getting Started

Warning: The MultiTech CT300 should be installed by a licensed electrician.

The following tools are recommended:

  • Proper PPE required
  • Standard hand tools necessary to remove the electrical panel cover
  • Multi-Tip Screwdriver

Step 1: Onboard the MTCT300

Using the device EUI and app key, add the device to your LoRaWAN® Network Server (LNS). For more instructions on this:

Step 2: Identify the Cable

Identify the conductor to install the MTCT300 on. Cables are grouped by Phases: L1, L2, L3. The table below shows the phase color codes for different countries and voltages. It is the installer’s responsibility to confirm the correct phases.

Wiring Color Codes



Step 3: Test the Cable

Test the conductor with a clamp-on ammeter to determine what current is flowing through the conductor. This will allow the installer to know what value should be seen on a visualization application. If the amperage limit is below the minimum amperage for normal operation this indicates that the Current Transformer is in low power mode and will likely not communicate on a regular basis without USB power.

Step 4: Pre-charge the MTCT300

It is recommended to pre-charge the MTCT300 before installing in a panel. Pre-charging the MTCT300 allows data to be sent to the customer system to verify that the MTCT300 works correctly. Pre-charging along with reading the amperage in the conductor with a clamp-on ammeter allows the customer to know that everything is working correctly. Pre-charging can be done using a USB-mini cable plugged into the MTCT300 communication module USB-mini port.

  1. Plug a USB wall charger into an outlet.
  2. Plug the USB cable into the USB wall charger.
  3. Plug the cable into the USB-mini port on the MTCT300.
  4. The MTCT300 will join the customer LoRaWAN Network Server (LNS) within one minute of plugging the USB charger into the USB port on the communication module. Charge the MTCT300 for at least three minutes before removing the USB cable if you want to have the MTCT300 device operate off of the capacitors.
  5. Observe the LED on the top of the MTCT300 communication module. Once the MTCT300 is powered, the RED LED will begin blinking a series of 20 blinks as the communication module boots up. After the boot-up, the device will attempt to Join the LoRaWAN Network Server (LNS). While trying to join the LNS, the LED will have (3) RED blinks. When the MTCT300 joins the LNS, the communication module LED will blink 2 RED Blinks. This is the normal operation state for the MTCT300. LoRaWAN packets with minute-by-minute circuit data will start flowing. Once joined to the LNS and data flow is confirmed, the installation has been completed successfully.

Step 5: Verify the Data

Using a visualization tool, view the data for the MTCT300 to make sure that correct data is transmitted.

LoRaWAN Data Format

Introduction

LoRaWAN (Long Range Wide Area Network) is a low-power, wide-area networking protocol designed for wireless communication between devices and centralized gateways. It operates on unlicensed radio frequencies (typically in the 868 MHz or 915 MHz ISM bands, depending on region) and is optimized for long-range, low-bandwidth applications such as remote sensing, monitoring, and control.

LoRaWAN is built on top of LoRa® modulation, which enables robust and energy-efficient data transmission over long range or under challenging radio environments such as electrical panels. The protocol defines secure communication, adaptive data rate (ADR), and network scalability, supporting a high device count per gateway.

LoRaWAN networks are typically structured such that devices communicate directly with one or more gateways. These gateways forward data to a LoRaWAN network server (LNS), which handles message deduplication, device authentication, and routing to customer applications.

Data Length Restrictions

LoRaWAN adaptive data rate (ADR) and variable modulation spreading enables tradeoffs between range/noise immunity and data throughput. Devices with good signal strength to the gateway will use efficient data rates and spreading factors to reduce the amount of airtime required to send data. Devices with poor signal will use settings that improve reception at the cost of longer airtime and lower throughput.

LoRaWANregional specifications limit maximum airtime for devices. This ensures fair access for all systems in highly contested radio frequencies. Because the MTCT300 reports data at a high rate compared to typical LoRaWAN devices, it is required that the data packets have limited size to keep the airtime under the regulatory limits in worst-case conditions.

Note that public LoRaWAN networks may throttle devices that violate their terms of use and often impose additional restrictions on airtime and uplink count.

MTCT300 Open-Source Codec

Verified open-source JavaScript codecs (data decoders) are available for a variety of major LoRaWAN network servers (LNS). When deploying the MTCT300 it is highly recommended that these be utilized over developing custom implementations when possible.

The codec’s are freely available on GitHub: https://github.com/the-real-vutility/payload-codecs.

MTCT300 LoRaWAN Port Field

LoRaWANframes contain a "FPort" field which accompanies data payloads. An FPort value of 0, which is reserved by specification, indicates that the payload contains a LoRaWAN protocol control command. FPort values 1 to 223 are application specific and may be defined by users.

MTCT300 sends and receives user-facing data on FPort 3. Data received on other ports will be discarded.

Troubleshooting

Status Flashing Codes

The MTCT300 contains a red LED light. Status is communicated via patterns of flashes described by the following table.

Flash Pattern Condition Device State
1 Flash every 10 seconds (or no light) MTCT300 is in measurement-only mode or unpowered

The capacitor voltage is low and the device may soon cease operation. Check that the module is seated securely in its socket on the current transformer and that sufficient current is flowing in the monitored circuit.

Depending on the current flow, low-power operation may be expected for some time after initial power-on.
1 Flash every 5 seconds Low power operation The device is functioning properly but the capacitor voltage has dropped below the full operation point. The rates of transmission and measurement have been decreased to conserve power.
2 Flashes every 5 seconds Normal Operation The device is functioning properly and is joined to a LoRaWAN network.
3 Flashes every 5 seconds LoRaWAN joining in progress The device is functioning properly and attempting to join a LoRaWAN network.
20 Flashes at 1Hz MTCT300 initialization

The device is initializing after reset.

Expected at power-on, occurrences during operation indicate reset due to error conditions.

Additional Troubleshooting Information

  • Using a visualization tool, ensure that the Signal-to-Noise Ratio (SNR) is a positive value, and that Received Signal Strength Indicator (RSSI) is greater than -115.
  • For cellular backhaul, make sure that the signal is strong enough. Note that bars on a phone do not always give a true indicator of the cell signal.
  • Make sure that there is enough current flowing in the conductor. Using a visualization tool, check to make sure that the supply voltage (capacitor voltage) is above 3.4V. The chart below shows the MTCT300 capacitor voltage (supply voltage) power levels for full operation, low power transmit, measurement only, and non-operational.

Power Harvesting Charge and Discharge

Typical Charge and Discharge

The MTCT300 begins charging its internal capacitor-based energy storage whenever current flows through the monitored circuit. Because the device’s processor, radio, and measurement circuitry require a minimum operating voltage, there is a brief period after energization during which the capacitor has not yet charged sufficiently for the device to function. During this time, the MTCT300 does not collect measurements or record current in its amp-hour totalization.

The length of this initial charge period depends directly on the amount of current in the circuit. Higher currents allow the capacitor to charge more quickly. For detailed behavior by model, refer to Appendix A: Charge Time and Current.



Short Load Interruptions

If circuit current is lost, the MTCT300 continues operating from the energy stored in its capacitor. As this energy is depleted, the device transitions through low-power modes to preserve operation. The amount of time a MTCT300 can function during an outage depends on how much excess energy it stored prior to the loss of current. In many cases, short outages will not affect the device’s ability to operate or measure current.

If the outage is brief and the capacitor does not fully discharge, the MTCT300 resumes normal operation without delay once current returns; there is no reinitialization or unmonitored period.

See Appendix B: Discharge Time for information on the holdover time of the MTCT300.



Long Load Interruptions

The MTCT300 will shut down completely if an outage is long enough that the capacitor becomes fully discharged. When current is restored, the device must undergo the initial charge period again before it can resume normal operation. During this time, circuit current is not monitored until the capacitor reaches the minimum operating threshold.

If the MTCT300 is used to monitor periodic loads where extended outages are common, it is recommended to supply external power via a 5V micro USB connection. This is only necessary when accurate amp-hour totalization is required, as it ensures continuous uninterrupted operation.

See Appendix B: Discharge Time for information on the holdover time of the MTCT300.



Capacitor Voltage Power States

The rate at which the internal capacitor is charged and discharged depends on the current flowing through the monitored circuit and the configuration of the MTCT300. In order to prevent the device from unexpectedly losing power while operating (causing data loss), the MTCT300 uses tiered power modes to regulate consumption of high power systems. These power modes and thresholds are described in the following:



Event Description
System Initialization The MTCT300 measurement circuitry requires a minimum of 2.1V to operate. Once the capacitor has charged to this value, the device initializes and begins measurement (MX), but does not currently have enough energy to operate the LoRaWAN radio.
Transmit(TX) Enable The capacitors contain enough energy to power the radio circuits without immediately draining the supply. The device will begin the LoRaWAN joining process and transmit data at a reduced rate to conserve energy.
Full Operation Enough energy is stored that the device can transmit and measure at full speed. The rates of transmit and measurement are configurable by LoRaWAN downlink.
Low Power Operation The device is not harvesting enough energy to maintain full operation. To prevent the device from unexpectedly losing power due to high consumption, the rate of transmit and measurements are reduced. This extends the operational limits of the MTCT300.
Transmit Disable There is no longer sufficient energy to operate the radio without interfering with the measurement circuitry. The MTCT300 will continue to monitor and record data, but will no longer transmit updates until increased power is available.
System Shutdown Below the 2.1V limit, proper operation of the measurement circuitry is no longer guaranteed and the device shuts down. When crossing this limit the device saves measurement values to an EEPROM storage device to prevent data loss.

Externally Powered Behavior

The MTCT300 can be powered by connecting a 5 Volt supply to its micro USB port. When external power is applied, the device’s internal capacitors charge rapidly regardless of whether current is flowing through the monitored circuit. This feature is useful for pre-charging the device during installation or for maintaining data reporting in the absence of load current.

During startup, the MTCT300 checks for the presence of external power. If detected, it immediately enters full operation, even if the capacitors are not yet fully charged. This check occurs only at power-on. If external power is applied to an already operational MTCT300 it will continue to transition through power states based on the capacitor charge level.

If external power is removed before the capacitors have reached sufficient charge, the device may shut off abruptly. To ensure uninterrupted operation after disconnecting external power, it is recommended that the connection be maintained for at least 30-60 seconds to allow the capacitors to charge.

Common Issues and Resolutions

Issue Cause Resolution
MTCT300 Not Operating Insufficient circuit current or initial charging period The MTCT300 does not have sufficient power to operate. This may be a temporary state while the capacitor initially charges, or there may be insufficient circuit current to maintain a charged state. Check circuit current and proper CT closure.
Inaccurate Low-Scale Readings Metered value below 1% of sensor rating Sensor accuracy decreases in the extreme low-end range. Use an appropriately sized device for the system.
Inaccurate Amp-Hour Totalization Periodic loads with long inactive time Each time the MTCT300 restarts due to insufficient current, there is an unmonitored initial charging period. These can aggregate into large offsets for loads that cycle routinely. Consider externally powering the MTCT300 over USB.
No Data Reported (Three Status Light Flashes) Device not joined to a LoRaWAN network Check the device onboarding to the LoRaWAN network server. Ensure that the antenna is screwed on completely. Reposition the MTCT300 antenna and/or gateway to increase signal strength.
No Data Reported (Two Status Light Flashes) LoRaWAN communication unreliable The device has joined the LoRaWAN network but there is insufficient signal strength for reliable communication,or significant interference from other wireless or electrical systems. Reposition the MTCT300 antenna and/or gateway to increase signal strength.
No Data Reported (One Status Light Flash @ 5s) Device in low-power transmit mode The device has insufficient power to maintain full rate transmit. Data will be sent once every 15 minutes. Check circuit current and proper CT closure.
No Data Reported (One Status Light Flash @ 10s) Device in low-power measurement-only mode The device has insufficient power to transmit and is measuring and recording data only. Check circuit current and proper CT closure.
MTCT300 Resets Periodically Failing LoRaWAN link check (i.e. LinkCheckReq & LinkCheckAns) The device cannot reliably communicate with the LoRaWAN gateway and is failing consecutive connection checks. This causes a two-hour reset interval. Reposition the MTCT300 antenna and/or gateway to increase signal strength.
