Westinghouse 626610R Limit Switch Manual Reset 250V

Product Description

The WESTINGHOUSE 626610R is a manual-reset, frame roll-out limit switch rated at 250 volts for use in electric heating units. Limit switches of this type serve as a thermal safety device, interrupting the circuit when an out-of-range temperature or roll-out condition is detected. The manual-reset design means the switch must be physically reset after a trip event, which helps ensure a technician inspects and corrects the root cause before the unit is returned to service. Licensed HVAC technicians and electric heating service pros are the typical installers and service personnel for this component.

This limit switch is applied in electric heating unit installations where roll-out protection is required. The frame roll-out designation indicates it is mounted at the heating element frame to detect flame or heat roll-out beyond the normal combustion or heating zone. It is suited for residential and light commercial electric heating applications where manual-reset safety controls are specified or required by code.

Key Features

• Manual-reset operation requires deliberate technician action after a trip, preventing automatic restart without inspection
• Frame roll-out mounting position detects heat or roll-out conditions at the heating element frame
• Rated at 250 volts for compatibility with standard electric heating unit circuits
• Acts as a thermal safety device to protect equipment and occupants from overtemperature conditions

Compatibility

Designed as an OEM-style replacement limit switch for electric heating units requiring a 250-volt, manual-reset, frame roll-out limit switch.

Installation Notes

Installation and replacement of limit switches should be performed by a licensed HVAC technician. Always disconnect and lock out power to the electric heating unit before removing or installing any electrical components. After replacing the switch, identify and correct the underlying cause of the original trip event before resetting and returning the unit to service. Follow all applicable local electrical codes and the unit manufacturer's service instructions.
