The Carrier HH12ZB150 is a factory-specified automatic reset limit switch designed for use in Carrier HVAC systems. This precision safety component monitors temperature levels to protect your heating system from overheating conditions, automatically resetting once temperatures return to a safe operating range.
Key Specifications
- Part Number: HH12ZB150
- Switch Type: Limit Switch with Auto Reset
- Circuit Configuration: SPST (Single Pole, Single Throw)
- Temperature Rating: L150F-40
- Open Temperature: 150°F
- Differential: 40°F
- Close Temperature: 110°F
- Brand: Carrier
How It Works
This SPST automatic reset limit switch opens the circuit when the sensed temperature reaches 150°F, shutting down the heating system to prevent damage from excessive heat. Once the temperature drops by 40°F to approximately 110°F, the switch automatically resets and closes the circuit, restoring normal system operation — no manual intervention required.
Why Auto Reset Matters
The automatic reset functionality makes this limit switch ideal for applications where temporary overheating conditions may occur. Rather than requiring a technician or homeowner to manually reset the switch after each event, the switch self-resets once conditions are safe, reducing downtime and service calls.
Compatibility & Application
This is a genuine Carrier OEM replacement part engineered specifically for Carrier HVAC equipment. Using an OEM-specified limit switch ensures proper fit, reliable performance, and maintained system safety standards. Always verify compatibility with your specific Carrier unit model before installation.
