Vector12-S (Encapsulated Poles,Spring Mechanism driven)

The Vector12-S withdrawable VCB features the following:

  • Phase-centre distances at 165mm for 1250A ratings, at 230mm for breakers with 2000A ratings and 280mm for breakers with ratings of 3150A and above.
  • Designed to be mounted within LKE's Vector-VMC12 metal-clad switchgear.
  • Encapsulated poles with vacuum interrupters embedded within the resin material of the pole housing to increase creepage distances and surface insulation between terminals.
  • Nominal current ratings of up to 3150A with natural cooling and higher ratings are available with fan assisted cooling.
  • Maximum breaking capacity of up to 40kA.
  • Driven by conventional spring mechanism capable of more than 50,000 operations.
