Supco L290 Thermostat 60T11 Style 610025

The Supco L290 Thermostat 60T11 effective 610025 is a snap-disc thermal switch used in such applications as furnaces, blower assemblies, and air handling units. It operates through a bimetal element that reacts to a heat rise, opening the circuit at 290F and closing again after cooling to 250F for reset. It is positioned on heat exchangers, blower housings, or discharge air paths inside the unit and wired into the safety circuit. Thermal response provides cutoff action during excessive temperature rise, stabilizes cycling behavior, and protects internal components from overheating during continuous furnace operation used in HVAC systems.
