The OSM outdoor circuit breaker (recloser) from Tavrida Electric is intended for automatic switching in power networks, and to serve as outdoor circuit breaker in power distribution stations for voltages up to 27 kV.
The OSM circuit breakers are distinctive by their highly reliable switching mechanism. Conventional circuit breakers use a rather complex operating mechanism for the transfer of forces from the actuator to the main contacts, and moving contacts are kept in ON and OFF positions by mechanical latches exposed to critical stresses which are the main reasons for defects.
The Tavrida Electric vacuum circuit breakers feature an extremely simplified switching mechanism, with particular focus on the minimization of the number of mechanical components.
