Outdoor vacuum load-break switch for railway applications - FSG II

        Single-pole outdoor vacuum load-break switch with magnetic actuator
       The FSG II, purpose-built single-phase load-break switch for 16.7 Hz railway power-supply implements the 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!
