Model W Series

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.
