Product Overview

Description

DW45 ACB,Intelligent circuit breaker

 

CE Indoor DC DW45 4 Pole 5000A Air Circuit Breaker Application

DW45 series intelligent breaker is applicable in the distribution network of AC 50Hz, rated voltage

of 400V and 690V and rated current from 630A~6300A, to distribute electric energy protection

circuit and prevent power equipments from 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.
