System Functions

Real-time monitoring

Leakage current-based electrical fire detection sensors enable real-time monitoring and display of the residual current in controlled circuits.

Alarm Protection Feature

Residual Current Electric Fire Monitoring Detectors can detect the residual current of electrical circuits. If the limit is exceeded, they emit audio-visual alarms. They can also cut off the power supply circuit within the specified time (can be set not to cut off) to ensure safe electricity use.

Communication Features

The residual current electrical fire detection sensors are equipped with RS485 communication bus and Modbus-RTU protocol, enabling network communication with our company's monitoring equipment host for remote management and maintenance.
