Vector12-M (PM-Actuator driven)

The VECTOR12-M is a cassette-type (withdrawable) 12kV Vacuum Circuit Breaker designed for the VMC12 metal-clad switchgear. Features:
  • Nominal current ratings of up to 2000A, with a maximum breaking capacity of 31.5 kA and a maximum short-time current of 31.5kA / 4 sec.
  • Well-designed interrupter housing provides ample ventilation of the vacuum interrupter assembly.
  • Re-inforced frame/chassis design results in the mechanical losses due to distortion of the VCB frame during closing is reduced to negligible levels.
  • Driven by a low-energy single-coil permenant-magnet actuator capable of more than 20,000 mechanical operations. (Special solution actuators capable of 250,000 operations are available at request.)
