Description

Overview
VF2-12 TYPE vacuum Circuit breaker , indoor high voltage switchgear suitable for 11/12kV. Threephase power system with 50Hz/60hz 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 withdrawable unit with a specially pushing framework. For meet the requirement of XGN2, GG1A cabinet, the fixed type breaker can be install additionally interlock.
