Medium Voltage
Metal Enclosed Switchgear

Vacuum Circuit Breakers (VCBs)

  • High performance, robust, draw-out removable breakers
  • Integral manual charging handle
  • Mechanical interlocks prevent withdrawal or insertion of the circuit breaker when main contacts are not open
  • Closing springs automatically discharge before moving the circuit breaker out of the enclosure
  • Circuit breaker cell mechanism maintains trip during insertion or withdrawal
  • Breaker cannot be electrically or mechanically closed when in the intermediate position
  • Cells are keyed to ensure only correct breaker rating can be installed in cell
  • High-speed operation – complete fault clearing in less than 3 cycles
  • Hermetically sealed vacuum interrupters protect contacts from corroding elements and contamination
  • Easy maintenance with contact wear indicator is provided on the vacuum interrupter moving stem
  • Periodic visual inspection with a feeler gauge is required to verify that the contacts have not worn out
