Description
The Weil McLain 510300014 Spill Switch is a safety control component used in boiler and heating systems to detect abnormal temperature conditions and protect equipment from unsafe operation in HVAC systems. It is designed to trip at approximately 240F, interrupting the control circuit, and it requires a manual reset after activation to restore operation. It is installed in compatible boiler assemblies during servicing or replacement procedures, where it connects to the safety circuit and monitors flue or combustion-related temperature conditions. It is a high-limit safety part that helps prevent overheating, ensures safe shutdown in an abnormal condition, and supports controlled boiler operation during heating cycles.
