Models A2, AA2, -A2, -AA2, A2R, AA2R

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.  Also available with normally open contacts (A2R, AA2R)

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.
