1. Principle The automatic reclosing circuit breaker/leakage protection switch automatically closes the circuit breaker when the MCB/RCCB accidentally trips, no need to manually close the circuit breaker, reduce manual maintenance costs, deal with faults in a timely manner, and improve circuit work efficiency. 2. Ideal Equipment The circuit breaker has built-in 3-times reclosing, and the warning message can be issued by auxiliary contact when continuous closing failure occurs within 15 minutes, which is an ideal equipment for circuit operation work. 3. Multi-function The leakage protection device has manual/automatic selector switch and mechanical/electronic double locking function, you can set the locking mode according to your needs. 4. Intuitive observationRemotely monitor the working status of the RCCB through the RS485 interface, reduce the load of the circuit breaker and provide better support for the circuit. 5. [Stable Switch] The leakage switch is driven by shaft so that it is more stable and reliable, it can be used with other accessories and its working status is indicated by LED.
