High Voltage Vacuum Circuit Breaker VBM-10-20(12.5)/630-1000 U2 for Energy Systems

Switches are designed for frequent switching operations in switchgear cells installed in power systems of three-phase current frequency 50Hz with isolated or compensated neutral, as well as in control cabinets of receivers of electrical energy of industrial enterprises. It is allowed to use switches for starting and switching off induction motors with squirrel-cage or phase rotor, as well as braking of these motors countercurrent and switching off slowly rotating electric motors. If it is necessary to operate the switches in conditions not provided for in the specifications, the plant has the possibility to modernise the switch at the request of the customer. Switches are supplied to all switchgear - construction enterprises of Russia, Belarus, Poland, as well as widely used to replace oil and low-oil circuit breakers that have exhausted their life, under the Retrofit programme in all switchgear and CSR previous years of production.
