drawer type ACB, up to 6300A DW45
Keyword:3P,4Pole, small volume, FH:Fixed type, DH:drawable type, Electric and manual operation,Intelligent controller:L,M,H, under voltage instantaneous(delay) release, and shunt releaseProduct Description
DW45/W1 series intelligent breaker is applicable in the distribution network of AC 50Hz, rated voltage
of 400V and 690Vand rated current from 630A~6300A, to distribute electric energy protection
circuit and prevent power equipmentsfrom harm of overload, under-voltage,short circuit and
single-phase earthing etc.
Provided with intelligent protecting function and precise selective protection, breaker can enhance
the dependability of power supply and avoid the unexpected power cut.
This product accords with the standard of IEC60947-2.
