Carrier HH12ZB150 Limit Switch R-134A the DPT2090-100G is calibrated forThe Carrier HH12ZB150 Limit Switch is a critical OEM safety component designed for precise thermal monitoring in high output furnace applications and residential air handlers. As a genuine Carrier L150F 40 temperature control, this switch is engineered to maintain system integrity by automatically interrupting the electrical circuit when internal plenum temperatures reach the 150F set point. This proactive thermal cutout prevents heat exchanger damage
