剩余的现有电路断路器

PIDresidual currentcircuit breaker (RCCB)is in conformity with the standard of IEC61008.The RCCB can cut off thefault circuit immediately onthe occasion of shock hazard or earth leakage of trunk ine.Thus, it is suitable to avoid the shock hazard and fire causedby earth leakage. The RCCB is mainly suitable for application in varieties of plants and enterprises, buildings, constructions. It can be used in circuits up to 1 phase 230V and 3 phase 400V 50/60Hz. RCCB is not suitable for application in DC pulse system.
