Hydraulic magnetic 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 over-load 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 infrequent switch-over of the circuit and illumination under normal conditions. They comply with IEC 157-1973.
