RCD(RCCB) Type B Residual Current Circuit Breaker is mainly used on solar or EV installations where protection from smooth DC is required in AC 50Hz circuit with rated voltage 400V and rated current up to 63A. In case of personal electric shock or when the grid leakage exceeds the specified value, the residual current circuit breaker can quickly cut off the power supply in a very short time for protection of the safety of people and electrical equipment . This product is suitable for various places such as industry, business, and domestic buildings
