ZN63A(VS1)-12C Indoor high-voltage side-mounted vacuum circuit breaker

Product Overview
The ZN63(VS1)-12C series indoor high-voltage vacuum circuit-breakers are three-phase,
50 Hz, 12 kV indoor switchgear designed for control and protection in industrial and
mining enterprises, power stations, substations and electrical installations, and are suitable
for applications requiring frequent operation. Featuring an integrated operating mechanism
and circuit breaker body, the design allows for use as a fixed installation unit or, when
fitted with a dedicated draw-out mechanism, as a draw-out unit. The main circuit section
utilises integral encapsulated busbars to achieve a compact, highly reliable and
maintenance-free circuit breaker. It can be fitted with centre-mounted draw-out switchgear
such as the KYN28A-12 (GZS), whilst the fixed version is compatible with the XGN
series of fixed switchgear.
