Vacuum Circuit Breaker 6 (10) kV Series VR1M for Electrical Circuit Protection

The switch is designed for switching of electric circuits in normal and emergency modes in networks of three-phase alternating current with frequency 50 (60) Hz with rated voltage 10 kV for systems with isolated or partially grounded neutral. Field of application The switch is designed to work in complete switchgear (switchgear) and chambers stationary single-sided service (CSR) internal installation for voltage class 10 kV. The switch is designed for installation in newly constructed switchgear substations, as well as for replacement of obsolete or exhausted its resource devices. Design features The switch uses vacuum chambers installed in insulating housings that protect them from mechanical damage, dirt and moisture, and a compact spring drive of a new design, in which the spring is automatically wound by an electric motor, as well as, if necessary, the handle of manual "winding".
