Indoor Vacuum Circuit Breaker
Description:
VS1-12(ZN63A) indoor high voltage vacuum circuit breaker is a three-phase AC 50 Hz indoor high voltage switchgear with rated voltage of 7.2-12kV. The circuit breaker meets the requirements of China's national standard gb1984-2003 "AC high voltage circuit breaker ", jb3855-1996 "3.6 ~ 40.5 kV indoor AC high voltage vacuum circuit breaker", d1403-91 "10-35 kV indoor high voltage vacuum circuit breaker ordering technical conditions" and relevant iec60694. IEC62271-100 standards, and has reliable interlocking function.
VS1-12(ZN63A) indoor high voltage vacuum circuit breaker can be operated frequently and has the ability of multiple breaking, and fast reclosing.
VS1-12(ZN63A) indoor high-voltage vacuum circuit breaker is designed as a front and back separate structure, which can be used as a fixed installation unit or as a separate handcart with a chassis car.
