earth leakage circuit breaker,
earth leakage breaker
4 pole earth leakage circuit breaker adjustable Current overload and leakage current protection voltage operated elcb
STG series adjustable residual current circuit breaker is suitable for AC 50/60Hz,230/400V circuit,prevents from overloading,short-circuit etc.On the occasion of shock hazard or earth leakage,it will trip immediately.At the same time,the rated current of overload protection can be adjustable.
The mccb can be sorted to C type (basic),L type (standard),M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity.
The mccb has the features small volume, breaking capacity high, electric arcing short ,anti-vibration. It is the ideal product for application in land and ship.
