Supco SHL507 Limit Switch
The Supco SHL507 Limit Switch is a professional-grade thermal protection component engineered for board-mounted applications in residential and commercial HVAC units. This SPST normally closed (NC) switch is designed to break the electrical circuit when temperatures reach the 140°F fixed open setpoint, preventing heat exchanger damage or unsafe operating conditions. Once the temperature drops to the 110°F fixed close temperature, the device utilizes an auto-reset mechanism to restore system continuity. With a 3.12-inch insertion length, this temperature limit control switch offers precise monitoring deep within the plenum or airflow path. As a direct replacement for S1-025-29041-005, the SHL507 ensures a high-reliability fit for technicians servicing York, Luxaire, and Coleman equipment. This UL recognized and CSA approved component provides the high-tolerance performance required for HVAC safety limit applications.
Key Benefits for Contractors
- Precise Thermal Calibration: Fixed 140°F open and 110°F close temperatures eliminate the need for field adjustments and ensure consistent safety parameters.
- Broad Compatibility: Functions as a direct OEM replacement for S1-025-29041-005, simplifying inventory for multiple furnace brands.
- Durable Construction: Board-mounted design with a 3.12" probe provides stable positioning in high-airflow environments.
- Industry Compliance: Meets strict UL and CSA safety standards for use in professional refrigeration and heating systems.
- Efficient Troubleshooting: The automatic reset feature reduces unnecessary service calls while maintaining critical overheating protection.
Common Questions
Is the Supco SHL507 a manual or automatic reset switch?
The SHL507 is an auto-reset limit switch. It will automatically re-close the circuit once the temperature falls to 110°F, provided the underlying cause of the high-limit trip is resolved.
What are the electrical specifications for this limit control?
This is an SPST (Single Pole Single Throw) fixed-temperature control. It is designed to be normally closed and opens on temperature rise at the specified 140°F threshold.
Will this work as a replacement for other 3-inch insertion limits?
While the 3.12" insertion length is common, you must verify that the 140°F open and 110°F close setpoints match your specific OEM requirements to ensure safe equipment operation.
