Supco L225 Snap Disc Auto Reset Limit Switch, 185°F Cut-in / 225°F Cut-out

Description

The Supco L225 is a precision-engineered snap disc temperature limit switch designed to protect HVAC and appliance systems from dangerous overtemperature conditions. With a fixed 185°F cut-in temperature and a fixed 225°F cut-out temperature, this switch delivers consistent, repeatable performance in demanding heating applications. Its open-on-rise switch action interrupts the circuit when temperatures exceed the cut-out threshold, providing reliable overheat protection. The auto reset function automatically restores operation once temperatures return to a safe level, eliminating the need for manual intervention and minimizing system downtime.

Built around proven snap disc technology, the L225 offers fast, positive switching action that resists contact bounce and ensures long service life. It is commonly used as a replacement limit switch in furnaces, heat pumps, air handlers, and other HVAC equipment where dependable high-limit protection is essential.
