RP151B

The Jennings RP151B three-phase vacuum contactor is a compact, normally open, three-phase device for use in equipment that requires a high speed interrupt. It is useful as an overload interrupter to 2000 Arms interrupting capacity. Special erosion-resistant contacts provide an operational load life of 250,000 maintenance-free operations at the rated 200 A current.

Features RP151B

  • Erosion-resistant contacts provide a minimum of 250,000 operations for long, maintenance-free life
  • 2000 Arms interrupting capacity – ideal for use in an overload interrupter
  • Three-phase, normally open operation provides high-speed interrupt
