Profile
The indoor high voltage vacuum circuit breaker
ZN63A(VS1)-12 is used as the indoor switch gear
in 12kV power system. It works as a protective and
controlling unit for the grid equipment and power
equipment in industrial enterprises, with the
advantages of high reliability and long life-span. It
is specially suitable for the frequent operation at
rated current or repetitiously open & close the
shorted circuit. It's widely used in the industries of
power,energy, petrochemicals, metallurgy,
manufacture, transportation, construction,
environment and so on.
The circuit breaker integrates the actuating
mechanism and the breaker into one body, which
may work as a fixed unit or a withdrawable unit
with the special movable structure. The according
interlock can be added to the fixed type breaker to
match the XCN2, GC1A cabinet.
