White-rodgers 90 249S1 Definite Purpose Contactor 2 Pole

Product Description

The WHITE-RODGERS 90 249S1 is a 2-pole definite purpose contactor designed for switching loads in HVAC and refrigeration control circuits. Definite purpose contactors serve as the primary switching device for compressors, condenser fan motors, and other high-draw loads in cooling and refrigeration equipment. This contactor is a line-voltage component installed by licensed HVAC technicians during new construction, equipment replacement, or service calls. Its 2-pole configuration handles the phase switching required in standard single-phase compressor circuits found across residential and light commercial equipment.

This contactor fits into control panels of residential and light commercial HVAC systems where a 2-pole switching device is required. Typical applications include split-system air conditioners, heat pumps, condensing units, and refrigeration equipment that rely on a definite purpose contactor to engage and disengage the compressor or fan motor on a signal from the thermostat or low-voltage control board.

Key Features

• 2-pole configuration for single-phase load switching in HVAC and refrigeration circuits
• Definite purpose design rated for the repetitive cycling demands of compressor and motor loads
• Compact form factor suited for installation inside condensing unit or equipment control panels
• Lightweight construction at 0.8 pounds for easy handling during field service

Compatibility

Designed as an OEM-style replacement 2-pole definite purpose contactor for residential and light commercial HVAC condensing units and refrigeration equipment requiring a standard 2-pole contactor configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit or equipment panel before removing or installing the contactor. Verify that coil voltage, pole rating, and load ampacity match the equipment nameplate requirements before energizing. Follow all applicable NEC guidelines for line-voltage component replacement in HVAC equipment.
