ZN63(VS1)-12 High Voltage Vacuum Circuit
BreakerApplicationZN63(VS1)-12 indoor high voltage vacuum circuit
breaker is used in the three-phase AC power system of frequency
50Hz, rated voltage 12kV. It is applied in the grid equipment, the
power distribution system of industrial and mining enterprises as
well as the places where requires repeated opening short-circuit
current and frequent operation.This circuit breaker adopts unibody
design of operating mechanism and circuit breaker technology, which
can not only be used as fixed installation unit, but also can
constitute the handcart unit with dedicated advanced
mechanism.ZN63(VS1)-12 is indoor medium-voltage solid type seal
vacuum circuit breaker, ZN63(VS1)-12 vacuum breaker suitable for
the insulation in the indoor air switch for 50Hz, rated voltage
12kV and below the grid from the control and protection,
ZN63(VS1)-12 vacuum circuit breaker and the frequent need for
short-circuit breaking current of occasions with very good
performance, fully meet the requirements of automatic re-closing
and have higher reliability and service life.Technical
