MCB SX2N  Hydraulic magnetic  circuit breaker is mainly suitable for overload and short circuit protection. It adopts hydraulic magnetic trip instead of bimetal. So it has a high sensitivity and the ambient temperature does also not affect it. 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 *0/*0Hz, rated voltage of single pole or double poles up to **0V, three poles up to **5V. They can also be used for an unfrequented switchover of the circuit and illumination under normal conditions. They comply with IEC *******3 BC********7 and BS ***1.
