Resideo DP3030B5003 Contactor

The Resideo DP3030B5003 PowerPro Definite Purpose Contactor is a robust 3-pole HVAC contactor designed for reliable switching in demanding condensing unit applications and refrigeration systems. Rated for 30 Amps with a 120Vac coil voltage, this unit features Silver Cadmium Oxide contacts to provide superior conductivity and resistance to welding under high-inductive loads. This model serves as the direct replacement for 90-161, ensuring a drop-in fit for older systems without requiring bracket modifications. The DPST configuration is housed in a terminal block that supports both 1/4" quick connects and #6 screws, offering flexibility for field wiring. Engineered to operate within a temperature range of -4°F to 149°F, this 30A definite purpose contactor ensures stable arc suppression and mechanical longevity in high-cycle environments, making it an essential component for central air conditioner repair and heavy-duty motor control.

• Universal Compatibility: Serves as a 120V replacement for 90-161 and other standard 30-amp, 3-pole footprints.
• Enhanced Durability: Silver Cadmium Oxide contacts extend the life of the unit by minimizing pitting and arcing.
• Flexible Installation: Features dual-purpose terminals with quick connects and screw lugs for rapid field deployment.
• Thermal Stability: Optimized for operation in extreme mechanical room or outdoor ambient temperatures.

Can I use a 24V coil contactor to replace the DP3030B5003?
No, this unit requires a 120V control circuit. Substituting a 24V coil into a 120V system will result in immediate coil failure.

What is the difference between this and a generic 3-pole contactor?
The Resideo PowerPro series is specifically tested for inductive motor loads, ensuring the contact bridge handles the startup inrush current of HVAC compressors without sticking.

Will this work for a 3-phase compressor?
Yes, as a 3-pole contactor, it is designed to switch all three legs of a 3-phase power supply simultaneously.
