Supco SRL250 Manual Reset Rollout Limit Switch 250F

Product Description

The SUPCO SRL250 is a manual reset rollout limit switch designed for residential and light commercial heating systems. Part of the SRL Series of bimetal temperature controls, it provides reliable high-temperature protection by cutting out at 250 degrees F. When the switch trips due to a rollout condition, it must be manually reset before the system can restart, giving the technician a clear indication that an unsafe condition occurred and was not a nuisance trip. The vertical 1/4 inch terminals support standard quick-connect wiring. This switch is manufactured in the United States by Sealed Unit Parts Co., Inc. and carries UL recognition and CSA approval.

Rollout limit switches are installed in gas furnaces and other fuel-fired heating appliances to detect burner flame rollout, a condition where combustion gases escape the heat exchanger area and reach components that could be damaged or create a fire hazard. The SRL250 is suited for applications where a 250 degrees F cutout temperature matches the OEM specification. Licensed HVAC technicians and gas appliance service technicians are the primary installers. The compact bimetal construction fits into tight plenum and burner compartment spaces common in residential furnaces.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional. Always shut off gas supply and disconnect electrical power to the furnace before removing or installing a rollout limit switch. After installation, investigate and correct the root cause of any rollout condition before manually resetting the switch and restoring power. Local codes and the appliance manufacturer's service documentation should be consulted for mounting location and orientation requirements.
