Carrier HH12ZB230 Limit Switch it provides the structural rigidityThe Carrier HH12ZB230 Limit Switch is a critical safety component designed for precise thermal monitoring in high output furnace and air handler applications. As an OEM Carrier furnace limit switch, this device features an automatic reset mechanism and is calibrated for an opening temperature range of 190F to 230F. This part is engineered to interrupt the burner or heating element circuit if the internal plenum temperature exceeds safe operating
