Description
Hydrqulic Magnetic Earth leakage Circuit Breaker is mainly for suitable for overload and short circuit protection. It adopt hydraulic magnetic trip instead bimetal . So it has a high sensitivity and it is also not effected by the ambient temperature. It is especially used for ilumination and distribution in industry and commerce. They are mainly used for overload and short-circuit protection within thecircuit of AC 50Hz/60Hz, rated voltage of single pole or double up to 240V, three poles up to 415V.
They can also be used for an unfrequent switch-over of the circuit and ilumination under normal conditions. They are comply with IEC 60947, VC8035, VC8036 and BS 3871 part 1.
