System Features

Real-time monitoring

Residual current-based electrical fire detection monitors can realize real-time monitoring and display of the remaining current in controlled circuits.

Alarm Protection Function

Residual current electrical fire detection sensors can detect the residual current in electrical circuits. If the limit is exceeded, they will emit an audible and visual alarm. 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 Function

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.
