Application
LBM10 series molded case circuit breaker(hereinafter referred to as circuit breakder) is suitable for distributing network of AC 50Hz(or 60Hz). RATED CURRENT 15~600A, rated insulation voltage 690V and rated working voltage 400V or below. It can be usedto distribute electric energy and protect the circuit and electric equipment against overload, short circuit and under voltage,under normal condition,the circuit breaker also can be used to switch the circuit infrequently. Circuit breakers of framesize 250A and below also can be used to protect motor or infrequently start motor.
The products are in conformity with GB 14048.2 GB 14048.4, IEC 60947-2 and IEC 60947-4 .
