Supco LD225 Limit Switch 185°F Cut-In 225°F Cut-Out SPDT Auto Reset

The Supco LD225 Limit Switch L225-40F is a temperature-activated safety control that monitors heat levels and changes electrical circuit status when the sensing point reaches its rated limit. Its mechanism opens or closes the circuit, controlling power flow to connected components when excessive heat is detected. Installed at the designated heat sensing mounting within the equipment assembly, the limit unit allows HVAC systems to control electrical responses according to preset temperature limits. Its adjustable sensing arrangement maintains temperature detection, provides circuit interruption when required, and supports proper coordination between safety controls and connected equipment.
