Milesight CT101 LoRaWAN Current Clamp for Energy Monitoring

The Milesight CT101 is a LoRaWAN® smart current transformer designed for remote current monitoring and energy usage analysis. It is part of the Milesight CT10x series and is suitable for applications where electrical current needs to be monitored without invasive wiring or power disruption.

For facilities managers, energy managers, electrical contractors and IoT solution providers, the CT101 provides a practical way to monitor electrical loads across buildings, plant rooms, equipment, distribution boards and critical assets.

Milesight describes the CT10x series as a LoRaWAN-enabled smart current transformer for monitoring energy and analysing consumption remotely, with a non-invasive clamp design for quick and safe indoor installation without de-energising a facility.

Key Facilities Management Uses

The CT101 is particularly useful for facilities management and monitoring where organisations need better visibility of electrical usage, equipment operation or abnormal current behaviour.

Typical Irish use cases include:

• Building energy monitoring
• Plant room monitoring
• HVAC load monitoring
• Pump and motor current monitoring
• Electrical distribution monitoring
• Machine usage monitoring
• Equipment fault detection
• Farm and agricultural equipment monitoring
• Commercial building energy visibility
• School, campus and public sector energy monitoring
• Warehouse and factory load monitoring
• Remote current monitoring for multi-site estates

The CT101 helps identify usage patterns, spot abnormal current conditions and support better energy management decisions.

100A Current Monitoring

The CT101 is the 100A model in the Milesight CT10x range. Milesight states that the CT101 is designed for typical applications where currents of up to 100 amperes are required.

This makes it suitable for many everyday facilities monitoring and energy management applications, including single electrical circuits, equipment feeds and building services loads.

Non-Invasive Clamp-On Installation

The CT101 uses a split-core clamp design, allowing it to be installed around a conductor without cutting cables or interrupting the circuit. Milesight highlights the CT10x as suitable for quick indoor installation without power interruptions, helping reduce installation time and disruption.

This is especially useful for live facilities, schools, commercial sites, farms and industrial buildings where downtime needs to be avoided.

Self-Powered LoRaWAN Operation

The CT101 is designed for self-powered operation, deriving power from the measured circuit, with USB Type-C available for power, configuration, console access or cable temperature sensor connection.

This reduces the need for battery maintenance and makes the device well suited to long-term monitoring projects.

LoRaWAN Wireless Monitoring

The CT101 communicates using LoRaWAN®, making it suitable for wireless monitoring across buildings, facilities and distributed sites. It supports standard LoRaWAN operation, including OTAA/ABP Class A, and is compatible with standard LoRaWAN gateways and network servers.

For TITAN customers, the CT101 can be deployed with LoRaWAN gateways such as the Milesight UG65 Indoor LoRaWAN Gateway for building and facilities monitoring projects.

Compatible LoRaWAN Network Servers

The Milesight CT101 can be used with standard LoRaWAN gateways and network servers. The device is also listed in The Things Network device repository as a Milesight smart current transformer for remote energy monitoring and consumption analysis.

Common LoRaWAN platform options may include:

• The Things Stack / The Things Industries
• ChirpStack
• AWS IoT Core for LoRaWAN
• Actility
• LORIOT
• Netmore
• Orbiwise
• Milesight IoT Cloud
• Milesight Development Platform
• Milesight gateways with built-in network server support

This gives customers flexibility to deploy the CT101 into new or existing LoRaWAN monitoring environments.
