Over-Temperature Protector

Design

Normally Closed

Load:

Resistive
Inductive

A creep-action thermostat/thermal protector with highest contact rating of all Model A Series thermostats.  Available with gold diffused contacts (A2, AA2) for use in low voltage/low current applications, or with fine silver contacts (-A2, -AA2) for 120 VAC applications.

FEATURES

  • Conductive bimetal construction; the bimetallic element carries the circuit current.
  • Creep action device; slow make/slow break switching action.
  • No built-in differential between the opening and closing temperature.
  • Case electrically alive; insulating sleeving is available. Preset calibration temperature; not adjustable in the field.
  • Available to open circuit on rise of temperature (normally closed), Models A2 and AA2, or close circuit on rise of temperature (normally open), Models A2 and AA2.
  • Available with gold diffused, fine silver contacts for use in low voltage/low current applications.
  • Available with same end termination, Models A2 and A2; or opposite end termination, Models AA2 and AA2.
  • Available with factory applied lead wires. Models -A2 and -AA2 are without gold diffused contacts

CONTACT RATINGS

  • 5 amps 120 VAC resistive
  • 5 amps 120 VAC inductive
  • 6 amps 12 VDC resistive

CALIBRATION RANGE

Available with nominal calibration temperatures from 5° C to 200° C.
