Trending Diversitech dpe403240 3-pole Contactor 40A 240V

The DIVERSITECH dpe403240 is a three-pole contactor rated for 40 amps at 240 volts with a 24-volt AC coil. Contactors of this type serve as the primary switching device in HVAC compressor and condenser fan circuits, opening and closing high-voltage load circuits in response to a low-voltage control signal. The 24-volt AC coil is the standard control voltage in residential and light commercial HVAC systems, making this contactor a direct fit for typical rooftop units, split-system condensers, and package equipment. UL and CSA listed for compliant installation. Licensed HVAC technicians handle installation as part of routine compressor circuit service.

This contactor is suited for residential and light commercial HVAC applications where a three-pole switching configuration is required. Three-pole contactors are used when all three legs of a three-phase load must be switched simultaneously, or in single-phase applications where a third pole is specified by equipment design. Typical install scenarios include condenser unit replacements, compressor contactor upgrades, and service calls where the existing contactor shows pitting, coil failure, or welded contacts. No compatible model numbers were specified in the product data.

Key Features

• 40-amp load rating handles compressor and condenser fan motor circuits
• 240-volt AC load voltage matches standard single-phase and three-phase HVAC equipment
• 24-volt AC coil integrates directly with standard low-voltage HVAC control boards
• Three-pole configuration switches all load legs simultaneously
• UL and CSA listed for code-compliant installation

Compatibility

Designed as an OEM-style replacement three-pole contactor for residential and light commercial HVAC systems requiring a 40-amp, 240-volt, 24-volt AC coil switching device.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit or package equipment before replacing a contactor. Verify that the replacement contactor coil voltage, load voltage, amperage rating, and pole count match the equipment wiring diagram before energizing. Follow NEC requirements for disconnect placement and wire sizing on the load side of the contactor.
