RMM1L Plastic case circuit breaker with residual current protectionDetailed product description：

The RMM1L series plastic shell circuit breaker with residual current protection (hereinafter referred to as the circuit breaker) is suitable for infrequent switching and motor starting in circuits with AC 50Hz rated working voltage of 400V and rated working current up to 225A. The circuit breaker has overload, short circuit, and undervoltage protection functions. It can also serve as indirect personal contact protection and equipment leakage protection, as well as prevent fire hazards caused by grounding fault currents due to equipment insulation damage. Circuit breakers with a rated residual operating current not exceeding 30mA can also be used as additional protection for direct contact when the protective device fails.
