<\/p>\nProduct Overview
\nThe ZN63(VS1)-12C series indoor high-voltage vacuum circuit-breakers are three-phase,
\n50 Hz, 12 kV indoor switchgear designed for control and protection in industrial and
\nmining enterprises, power stations, substations and electrical installations, and are suitable
\nfor applications requiring frequent operation. Featuring an integrated operating mechanism
\nand circuit breaker body, the design allows for use as a fixed installation unit or, when
\nfitted with a dedicated draw-out mechanism, as a draw-out unit. The main circuit section
\nutilises integral encapsulated busbars to achieve a compact, highly reliable and
\nmaintenance-free circuit breaker. It can be fitted with centre-mounted draw-out switchgear
\nsuch as the KYN28A-12 (GZS), whilst the fixed version is compatible with the XGN
\nseries of fixed switchgear.<\/p>\n
