Outdoor Vacuum C.B. for Railway Applications - FSK II

        Single or two-pole outdoor vacuum breaker with magnetic actuator
        The FSK II, purpose-built single-/two-phase breaker for railway power-supply, builds on the success of the FSK I, vacuum breaker used worldwide. The major change is the implementation of maintenance free magnetic actuator and maintenance free electronic controller without auxiliary switches and with sensors. The result is a proven technology maintenance free breaker which functions so reliably it can simply be forgotten about!
       Breakers can be delivered as loose equipment or integrated into Compact FSKII modules.
