A snap-action thermal protector with the highest contact ratings of any of our controls.  Suitable for use on 120 & 240 VAC loads.  Available with variety of bimetallic elements to enhance performance characteristics when used in protection on inductive loads.

Features


  • Conductive bimetal construction; the bimetallic element carries the circuit current for maximum current sensitivity under short circuit conditions.
  • Snap action device, quick make/quick break switching action.
  • Temperature differential between opening and closing may vary from 20° C to 70° C depending upon the no-load calibration temperature.
  • Preset calibration temperature; not adjustable in the field.
  • Case electrically alive; insulating sleeving is available.

Contact Ratings


  • 20 amps 120 VAC resistive
  • 10 amps 240 VAC resistive
  • 50 amps 120 VAC inductive
  • 37 amps 240 VAC inductive

Calibration Range


  • Available with nominal calibration temperatures from 70°C to 150°C.
