The Supco L130 Limit Switch L130-15F is a temperature-sensitive safety control that opens or closes an electrical circuit based on fixed thermal thresholds. It operates through a bi-metal disc that reacts to heat buildup, switching the circuit off and restoring operation after cooling to the reset range. used in HVAC systems including furnaces, air handlers, and heating blower assemblies, it is typically mounted on heat exchangers or discharge air sections inside the unit. During setup, it is secured to a designated mounting point and wired into the furnace safety circuit.
