ZN63A(VS1)-12 Indoorac high voltage vacuum circuit breaker

Product Overview
The ZN63(VS1)-12 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.
