Application
YFM2LE series leakage circuit breaker (hereinafter referred to as circuit breaker) is a new type of circuit breaker with international advanced design and manufacturing technology,with insulation voltage 800V,it is suitable for circuit of AC50Hz,rated working voltage 400V,rated working current 400A,used to switch the circuit and start the motor infrequently.This series of circuit breakers has overload,short-circuit and under-voltage protection device,which can protect the line and power equipment from being damaged,meanwhile,it provides indirect contact protection for person,and it also can protect the equipment from possible fire risks caused by long-standing earth fault that can not be detected out by over-current protection device.According to the rated ultimate short-circuit breaking capacity,the circuit breakers can be devided into:L type(higher breaker type) and M type(high breaking type) two types.This series of circuit breakers is featured with compact volume,high breaking,short flashover,vibration proof and so on.This series of circuit breakers is featured with compact volume,high breaking,short flashover,vibration proof and so on.This series of circuit breakers can either be vertical installed or horizontal installed.The product is in accordance with GB14048.2 and IEC60947.2.
