Supco dp502403 Contactor 50A 3-pole 240V

Product Description

The SUPCO dp502403 is a 3-pole definite-purpose contactor rated at 50 full load amps (FLA) with a 240-volt coil, designed for use in HVACR systems. It switches compressor and condenser fan loads in residential and light commercial equipment, handling up to 65 amps resistive load (RLA). The compact universal footprint is engineered to replace the most common OEM contactor brands without modification. Licensed HVAC technicians install this device as a direct service replacement when an existing contactor shows signs of pitting, welded contacts, or coil failure.

This contactor is suited for 240-volt HVACR applications including central air conditioning condensing units, heat pump systems, and commercial refrigeration equipment. Its operating temperature range of -40 degrees F to 150 degrees F supports installations in both extreme cold climates and high-ambient equipment rooms. The 3-pole configuration is common in three-phase light commercial systems and in split-phase residential compressor circuits requiring a dedicated neutral switching leg.

Key Features

• 50 FLA rating handles standard residential and light commercial compressor loads
• 65A resistive load amperage (RLA) provides headroom for inrush and resistive circuits
• 240-volt coil compatible with standard low-voltage HVACR control boards
• 3-pole design suits three-phase and split-phase applications
• Wide operating range of -40 degrees F to 150 degrees F for varied installation environments
• Compact universal form factor replaces most common OEM contactor brands

Compatibility

Designed as an OEM-style replacement contactor for HVACR condensing units and refrigeration equipment requiring a 3-pole, 50A, 240-volt definite-purpose contactor. Compatible across common brands per the universal compact design noted by the manufacturer.

Installation Notes

Installation must be performed by a qualified HVAC technician. Disconnect and lock out all power to the condensing unit before removing the existing contactor. Terminal connections require torquing to 35 inch-pounds — use a calibrated inch-pound torque driver to avoid under- or over-tightening. Verify coil voltage matches the control circuit before energizing the unit.
