JM1LE

JM1L series residual current circuit breakers (hereinafter referred to as circuit breakers) are mainly suitable for distribution networks  with AC 50Hz, rated voltage AC400V, and insulation voltage up to 800V. 

They are used to provide indirect contact protection for people,  prevent fire hazards caused by equipment insulation damage and ground fault currents, and can be used to distribute electrical energy  and protect circuits and power equipment from overload and short circuits, It can also be used for infrequent switching of circuits and  infrequent starting of motors. 

The working power supply of the conventional leakage protection module with residual current protection  circuit breaker is sampled as two phases. This series of circuit breakers is three-phase. If any phase is missing, the leakage protection  module of the circuit breaker can still work normally; The rated residual operating current In and maximum disconnection time can be  adjusted on-site according to actual conditions; When the phase voltage drops to 50V, the leakage protection module can still operate  normally and has a leakage alarm output function.

 JM1L Series MCCB ELCB 1、Scope of use The product meets the standards of IEC60947 and GB14048.2
