Manufacturer , Earth Circuit Breaker, Leakage Adjustable MCCB
GENERAL
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.

A voltage-operated ELCB has a second terminal for connecting to the remote reference Earth connection.
The Earth circuit is modified when an ELCB is used; the connection to the Earth rod is passed through the ELCB by connecting to its two Earth terminals. One terminal goes to the installation Earth CPC (circuit protective conductor, aka Earth wire), and the other to the Earth rod (or sometimes other type of Earth connection).
