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.
