Supco SRL350 M/R SPST Rollout Switch 350°F

The Supco SRL350 Manual Reset Rollout Limit Switch 350°F is a thermal safety control that is incorporated in HVAC systems and opens a single-pole single-throw contact when the system detects excessive heat. It operates based on a calibrated temperature-sensitive mechanism that reacts at the designated temperature to prevent overheating of burners, heat exchangers, and other components in the vicinity. This rollout switch is installed in the control circuit, where heat can build up to increase the safety of the system by reducing the number of system parts and is used to ensure the safety of the system.
