Description
The Supco SHL512 is a board-mounted general purpose limit switch engineered for precise temperature control and reliable overheat protection in HVAC and appliance applications. With fixed open and close temperature setpoints, this auto-reset switch provides consistent, repeatable performance without manual intervention after a fault condition clears.
Key Features
- Fixed Open Temperature: 170°F — trips the circuit open when this threshold is reached
- Fixed Close Temperature: 150°F — automatically resets and closes the circuit as temperature drops back down
- SPST Normally Closed (NC) switch configuration for fail-safe operation
- Auto Reset function eliminates the need for manual reset after the temperature returns to safe range
- 3.12″ insertion length for secure board-mounted installation
- Designed for board-mounted general purpose limit switch applications
Application
The SHL512 is ideal for use in furnaces, air handlers, and other HVAC equipment where overheat protection is critical. Its normally closed SPST design ensures the circuit remains complete under normal operating conditions and opens only when the 170°F threshold is exceeded, protecting downstream components from heat damage.
