JB3855 - 1996 3.6 - 40.5kV VS1 High Voltage MV VCB / Rated Power of Closing 80W
1 Summary
VS1(ZN63A) series vacuum breaker is of indoor high voltage switchgear suitable for 12kV .
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.
