Detailed Product Description

24Kv  VS1 ( ZN63A ) Vacuum Circuit Breaker For Meet Requirement of XGN2, GG1A Cabinet
1Overview

VS1(ZN63A) series vacuum breaker is of indoor high voltage switchgear suitable for 24kV .Three-phase power system with 50Hz frequency in order to protect and control electrical appliances,  

and especially suitable for frequent operation at rated current or incessant 

open circuit due to unique advantages of vacuum circuit breaker.

Spring operating mechanism and breaker body parts adopt integration design.

Thank for this design,  breaker not only can be a fixed installation unit ,  

but also can be a withdraw-able unit with a specially pushing framework.

For meet the requirement of XGN2, GG1A cabinet ,  

the fixed type breaker can be install additionally interlock.
