Why does the CKW55 circuit breaker not operate after it is not powered?
Asked by: Green 238 views Hardware
After the 380 voltage is applied to the circuit breaker, the individual modules are not reflected, and the energy storage is not responding.

The non-operating current refers to the current value that can be operated for a long time without tripping. The operating current refers to the current value that exceeds a certain current to cause it to trip. The larger the value exceeding the current, the faster the circuit breaker trips, and the leakage current is 50. Tripped at mA, less than 25 mA does not jump; the second 100 mA trips, below 50 mA does not jump; the third is also the reason.

CKW55 series circuit breakers are intelligent universal circuit breakers with internal structure Complex, in addition to the tripping device, there are transmission mechanism, operating mechanism and intelligent controller. When the modules are not reflected after power-on, most of them are faulty inside the intelligent controller, only professional electrical technicians are required to deal with it. what.
