Over-Temperature Protector

Design

Normally Closed

Load:

Resistive
Inductive

A snap-action, self-hold thermostat for motor and appliance applications. In a fault condition, the Model JS opens the circuit and an internal heat source holds it in an open condition until power is removed, and the unit is allowed to cool. The thermostat then resets, allowing continued operation.

FEATURES

  • Snap-action device for quick break switching action.
  • Internal heat source provides a low profile design for better fit into tight spaces.
  • Self-hold functionality available for both 120 VAC and 240 VAC applications
  • Conductive bimetal construction; the bimetallic element carries the circuit current for maximum current sensitivity. Various resistances of bimetal available.
  • Preset calibration temperature; not adjustable in the field.
  • Case electrically alive; insulating sleeving available.
  • Available with or without factory applied lead wires.
