Appications of Miniature CircuitBreaker:
Hydraulic / magnetic miniature circuit breaker is mainly suitable for overloadand short circuit protetion. It adopts hydraulicmagnetic trip instead of bimetal. So it has a high sensitivity and it is alsonot effected by the ambient temperature. It isespecially used for illumination and distribution in industry and commerce. Itis mainly used for overload and short circuit protection within the circuit ofAC 50Hz/60Hz, rated voltage of single pole or double poles up to 240V, threepoles up to 415V. It can also be used for an unfrequentswitch-over of the circuit and illumination under normal conditions. Miniaturecircuit breaker complies with IEC 157-1973 BC 4752-1977 and BS 3871.
