Request DatasheetOverview
Vacuum circuit breakers switch in a sealed interrupter, so the contacts do not oxidise and the maintenance interval runs into thousands of operations. Supplied on a draw-out truck with motor-wound spring mechanism, anti-pumping relay and trip-circuit supervision, the panel is wired for local and remote control and can be integrated with substation SCADA.
