Supco Manual Reset Limit Switch F SPST Rollout Thermostat

The Supco Manual Reset Limit Switch (also called a flame rollout switch or rollout thermostat) is an SPST bimetal temperature control. It is built for furnace and heating-equipment safety circuits. The SRL series uses a compact 1/2" bimetal design that is reliable and cost-effective, and it works as a replacement limit or rollout thermostat.

Key Features:

• Single pole, single throw (SPST) switch that opens when temperature rises
• Manual reset: after a trip, the switch stays open until its reset button is pressed
• Bimetal disc senses temperature and separates the contacts quickly, for long service life
• Rated for loads up to 10 amps at 250 VAC
• Uses 36T electrical ratings in a compact 1/2" style
• UL recognized and CSA approved
• Offered in a range of cut-out temperatures to suit most heating applications

When the flame rollout switch trips on excess heat, the furnace shuts down and stays off until the switch is reset. This adds a layer of protection in gas-fired furnaces, unit heaters and rooftop units. Choose the variant whose cut-out temperature matches the equipment's original control.
