Westinghouse 626487R Limit Switch 0.5 in 140-190F Hvac R

Product Description

The WESTINGHOUSE 626487R is a thermal limit switch designed for use in HVAC and refrigeration systems. It monitors temperature within the unit and interrupts circuit continuity when a preset threshold is reached, protecting equipment from overtemperature conditions. The switch operates with a reset point of 140 degrees F and an activation point of 190 degrees F, and it features a 0.5 inch diameter form factor suited to standard mounting configurations. Licensed HVAC technicians and refrigeration mechanics install this component as part of routine service and safety-circuit maintenance.

This limit switch is suited for residential and light commercial HVAC and refrigeration equipment where thermal overload protection is required. It fits into systems that use a 0.5 inch diameter limit switch mounting point. Typical applications include forced-air furnaces, air handlers, and refrigeration units where a safety cutout is needed to prevent heat exchanger or component damage from sustained elevated temperatures.

Key Features

• Activation temperature of 190 degrees F with a reset temperature of 140 degrees F
• 0.5 inch diameter body fits standard limit switch mounting locations
• Interrupts circuit on overtemperature to protect HVAC and refrigeration components
• Designed for direct OEM-style replacement in HVAC and refrigeration applications

Compatibility

Designed as an OEM-style replacement limit switch for HVAC and refrigeration equipment requiring a 0.5 inch diameter thermal limit switch with a 140 to 190 degrees F operating range.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic. Disconnect all power to the unit at the breaker or disconnect switch before removing the existing limit switch or handling any wiring. Verify the replacement switch matches the original mounting diameter and temperature ratings before installation. Follow all applicable local mechanical and electrical codes during service.
