Westinghouse 626503R Limit Switch 0.5 in 245-285 Degrees F Hvac

Product Description

The WESTINGHOUSE 626503R is a limit switch designed for use in HVAC and refrigeration systems. 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.

This 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.

Key Features

• 0.5 inch diameter form factor fits standard limit switch mounting locations in HVAC and refrigeration equipment
• Temperature operating range of 245 degrees F to 285 degrees F for high-temperature cutout applications
• UL applicable standard rating confirms compliance with recognized electrical safety requirements
