Feature:1. When a person gets an electric shock or the grid leakage current exceeds the specified value, the circuit breaker can quickly cut off the faulty power supply to protect person and electrical safety.2. Suitable for both sine AC residual current and pulse DC residual current, very practical.3. Can also be used for infrequent switching of circuits and infrequent starting of motors.4. This durable circuit breaker is made of premium materials with IP20 protection grade.5. Allows for flexibly application in various places, such as homes, factories, hotels and so on.Specification:Item Type: Residual Current Circuit BreakerStandard: IEC/EN 61008.1, IEC/EN 62423Type (detected leakage form): Rated Current Input: 63ASpecification: 4pRated Voltage Ue: 4P: 400VInsulation Voltage Ui: 500VRated Sensitivity In: 0.03A, 0.1A, 0.3A.Rated Remaining Connecting and Breaking Capacity: 500(In=25-40A), 630(In=63A).
