Milesight CT303 Smart Current Transformer

The Milesight CT303 is a three-phase LoRaWAN® smart current transformer designed for remote energy monitoring and consumption analysis. Its non-invasive clamp design allows quick and safe installation without de-energizing the monitored equipment, while its compact design makes it suitable for a variety of indoor applications.

The CT303 supports real-time RMS current monitoring, threshold and overrange alarms, and optional energy consumption reporting. It is self-powered from the monitored conductor and supports an external temperature sensor for cable temperature monitoring, making it well suited for smart buildings, equipment monitoring, and machine failure prevention.
