High-voltage vacuum circuit breakers VS-AE-12 are devices designed for commutation of electrical circuits under normal and emergency conditions in three-phase AC networks, 50 Hz frequency, with a nominal voltage of up to 10 kV.

Field of application – circuit-breakers are used in the cells of the switchgear of internal and external installation, as well as in the chambers of SAC, both in new construction and when replacing the switches of old years of production. At the heart of the design solution of the circuit-breaker, is the use of electric motor drives mechanically connected to the shaft. The circuit-breaker is switched on and off by means of breaker mechanism.

AC isolators - are designed to turn on and off the de-energized sections of the electrical circuit, for safe work on the disconnected sections and their grounding with stationary grounding knives.
