Limit switches in these applications serve as safety controls, interrupting a circuit when a monitored temperature reaches a set threshold. The 626503R features a 0.5 inch diameter form factor and operates across a temperature range of 245 degrees F to 285 degrees F. Licensed HVAC technicians and refrigeration service professionals install this component as part of system overheat protection or high-temperature cutout circuits. It carries a UL applicable standard rating, confirming it meets recognized safety requirements for electrical components in heating and cooling equipment.\u003c\/p\u003e\n\u003cp\u003eThis limit switch is suited for residential and light commercial HVAC and refrigeration equipment where a compact 0.5 inch diameter switch is required. It is typically found in furnaces, air handlers, heat pumps, and refrigeration units where temperature-activated circuit interruption is critical to system safety. Installers replace failed or out-of-spec limit switches during routine service calls or as part of a heat exchanger or burner assembly inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5 inch diameter form factor fits standard limit switch mounting locations in HVAC and refrigeration equipment\u003c\/li\u003e\n  \u003cli\u003eTemperature operating range of 245 degrees F to 285 degrees F for high-temperature cutout applications\u003c\/li\u003e\n  \u003cli\u003eUL applicable standard rating confirms compliance with recognized electrical safety requirements\u003c\/li\u003e\n  \u003cli\u003eDirect replacement style for limit switch service in HVAC and refrigeration systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement limit switch for HVAC and refrigeration equipment requiring a 0.5 inch diameter limit switch rated in the 245 degrees F to 285 degrees F operating range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified refrigeration service professional. Always disconnect and lock out electrical power to the unit before removing or installing a limit switch.
