STO Electric Leakage Circuit Breaker , Mini Overload Protection 4 Pole ELCB
GENERAL
STO(PG) 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 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).
