Residual moulded case circuit breaker HKKM2L

HKKM2L Residual moulded case circuit breaker is suitable for use in circuit of rated voltage 380V AC,50Hz, and rated current up to 600A, as an electrical leakage protecting device to man. It also can be used to avoid fire caused by bad insulation of electrical aparatues and earthing faults. The breaker has various protections, protecting loads from over-load, shor-circuit, and over voltage. In the circuit, the breaker is usually used to be isolator for non-frequently switching. Being of small cubicle, high breaking capacity, short arcing distance, having isolating function, time delay function, residual current protecting function, the breaker can not be connected to circuit up and down. The connection must be following correct diagram that is terminal 1,3,5 connect to power lines and terminals 2,4,6 connect to load. Applied standard: IEC60947-2;GB14048.2 and standards.
