Milesight Smart Current Transformer CT310-868M (LoRaWAN®, 1000A RMS, IP30)

The Milesight CT310-868M is an advanced LoRaWAN® smart current transformer engineered for accurate, safe, and remote monitoring of electrical systems. It measures RMS current with a high 3.3 kHz sampling frequency, ±1% accuracy, and a fine 1 mA resolution, making it ideal for industrial energy analytics, predictive maintenance, and building energy management.

Supporting a primary rated current of 1000 Arms, the CT310 is suitable for heavy machinery, distribution boards, power lines, and commercial electrical installations. Its non-invasive clamp design allows installation without powering down equipment, drastically reducing downtime and installation costs.

Equipped with an NTC temperature sensor, the CT310 can also measure cable or environmental temperature within -20°C to +100°C, improving diagnostic capabilities. The device also supports threshold alarms, overrange alarms, and FUOTA (Firmware Update Over the Air).

The CT310 transmits data via LoRaWAN® OTAA/ABP Class A and is compatible with all standard LoRaWAN® gateways and platforms, including the Milesight IoT Cloud. Power is supplied via induced current or alternatively USB Type‑C, enabling flexible deployment.

Its durable PBT+PC UL94 V0 flame‑retardant housing, compact form factor, and cable‑tie mounting ensure easy use in control cabinets, energy panels, and industrial environments.

Typical applications include:
– Smart building energy monitoring
– Industrial load monitoring
– Machine failure prediction
– Power distribution oversight
– Non-invasive current sensing
– Industry 4.0 and IoT deployments
