Description
Supco SRL260 Manual Reset Rollout Limit switch is a temperature-operated safety control in HVAC systems, senses excessive heat, and opens a single-pole, single-throw circuit at 260°F to interrupt current flow to preclude an insecure condition. It works by having a thermal sensing element that reacts to high temperatures and opens the contact mechanically, preventing power flow when limits are reached. Installation is a process of connecting the limit switch to the heating unit control circuit at a point where heat can accumulate.
