CT303 - LoRaWAN Current Sensor 300 A - Milesight

The Milesight CT303 is a LoRaWAN current sensor for measurements up to 300 A. It allows monitoring of RMS current and cumulative current on a conductor, with non-invasive clamp installation suitable for sites already in operation.

Current Measurement

The CT303 is designed to monitor an electrical circuit or equipment without modifying existing wiring. It can be used to detect consumption drifts, track operating cycles, or trigger alerts when a threshold is exceeded.

LoRaWAN Transmission

The sensor communicates via LoRaWAN in Class A on the 868 MHz band. It can be integrated into a LoRaWAN gateway and a compatible IoT platform to centralize energy data and use it in a supervision dashboard.

Installation and Power Supply

The CT303 is self-powered by induced current, with a 5 V USB Type-C power supply possible as needed. Configuration is done via USB Type-C or downlink. The sensor is designed for indoor use with an IP30 rating.

Applications

The CT303 is suitable for commercial buildings, electrical cabinets, industrial equipment, technical rooms, and sites requiring energy monitoring up to 300 A.
