MCB SA1-G3 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 50/60Hz, rated voltage of single pole or double poles up to 240V, three poles up to 415V. They can also be used for an unfrequented switchover of the circuit and illumination under normal conditions. They comply with IEC 157-1973 BC4752-1977 and BS 3871.
