Indoor vacuum circuit breaker VVE-SESH-10 with spring-motor drive, for voltage class 10 kV AC, three phase, 50 Hz. The best choice for power distribution networks. Ideally fits in KRU-SESH-59, KRU-SESH-63, KRU-SESH-70 and KSO-SESH-298M.
VVE-SESH-10 are intended for switching of high-voltage three-phase AC circuits in nominal operating mode of installation, and also for automatic cutoff of such circuits upon short-circuit and overload arising in emergency modes.
It is used only within integrated solutions of Electroshield Samara.
