Vibration Dampening: Precision manufacturing helps minimize harmonic resonance and noise during the blower motor duty cycle

High Current Rating: Rated for up to 30A inductive load

It functions as a primary safety device

Use a multimeter to check for resistance (ohms) across the coil terminals

Reduced Downtime: Simplifies field repairs of MP953 series actuators without requiring a full unit replacement

Johnson Controls A11A-1 Freezestat Els PW 17895 Vibration Dampening: Precision manufacturing helpsThe Johnson Controls A11A 1 is a robust low temperature cutout freezestat designed to provide failsafe protection for hydronic coils, cooling coils, and liquid handling pipes. Featuring a manual reset mechanism, this SPST open low control ensures that systems remain offline following a low limit event until a technician can verify field conditions. The unit utilizes a 20 foot vapor charged sensing element that triggers the internal snap acting
