Vacuum Circuit-Breaker Indoor vacuum circuit-breakers are designed for 27.5 kV rated voltage and 1250 A rated current. Circuit-breakers require little maintenance. It is recommended to make visual inspection and periodic cleaning of insulation parts and greasing of drive mechanism. It is possible to control circuit-breaker manually by pushing buttons, or electrically (release mechanism). Actuator's drive reloads energy storage mechanism or coil spring after response. In addition to release mechanisms switching module also includes interlocks. Last switching operation is always switching off....
