Feature

  • UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment
  • Magnetically actuated switching design gives superior performance with free-swinging vane which attracts a magnet within the switch body, actuating a snap switch with no bellows, springs, or seals to fail
  • Leak proof body and vane constructed of tough durable polyphenylene sulfide which has excellent chemical resistance
  • A full size trimmable vane is provided with molded-in graduations
