Product Description

Spare Parts of Acb  3P 4P 6300A Intelligent Universal Fixed and drawout type ACB Automatic switch AC690V Low Voltage Air Circuit Breaker:

 

Product Description

We provide all sets of sparts for ST45(DW45) and finished products;

ST45(DW45)series intelligent air circuit breaker (hereinafter called ACB) are applied to the network circuit of AC 50 Hz, rated voltage 400V, 690V and rated current between 400A and 6300 A. Mainly used foe distributing energy and protecting the circuit and power supply device against short-circuit, under-voltage, single-phase ground fault, etc. The ACBS has intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.

The products conform to IEC60947-2, IEC 60947-4 standards.
