Application
Hydraulic magnetic miniature circuit breaker are mainly suitable for overload and short circuit protection. It adopts hydraulic magnetic trip instead of bimetal. So it has a high sensitivity and it is also not effected by the ambient temperature. It is especially used for illumination and distribution in industry and commerce. They are mainly used for overload and short circuit protection within the circuit of AC 50Hz/60Hz, rated voltage of single pole or double poles up to 240V, three poles up to 415V. They can also be used for an unfrequent switch-over of the circuit and illumination under normal conditions. They comply with IEC 157-1973.
