Resideo DP3050A5002 Contactor

The Resideo DP3050A5002 is a heavy-duty 3-pole definite purpose contactor engineered for demanding HVACR applications, providing reliable switching for induction motors, compressors, and heating elements. Built for high-amperage performance, this 50 amp contactor features silver cadmium oxide contacts to ensure superior conductivity and long-term durability in high-cycle environments. Operating on a 24Vac coil, the unit utilizes DPST switching and is equipped with 1/4" quick connects and #6 screws for secure, efficient field wiring.

Designed to withstand extreme mechanical stress, this PowerPro contactor maintains a robust -4/149 degree temperature range, making it ideal for rooftop units and industrial refrigeration systems. For service technicians performing field upgrades or repairs, the DP3050A5002 serves as a high-spec direct replacement for 8910DPA53V14 and 92-459, ensuring seamless mechanical and electrical compatibility. Its encapsulated shrouded coil design protects against moisture and environmental contaminants, reducing the risk of premature coil failure on the job site.

Key Benefits:

• High Ampacity Rating: Rated for 50 Amps resistive and 40 AFL, suitable for large-scale motor and compressor loads.
• Universal Compatibility: Specifically designed as an interchangeable HVAC contactor with multiple mounting slots for easy retrofitting.
• Enhanced Durability: Silver cadmium oxide contacts resist welding and pitting under high-load starting conditions.
• Environmental Protection: Shrouded coil architecture ensures reliable operation in high-humidity and high-temperature HVAC environments.
• Standardized Wiring: Dual 1/4" quick-connect terminals and lug connectors facilitate fast, error-free installation for the contractor.

Common Questions:

Is this contactor compatible with A2L refrigerants?

Yes, the construction of the DP3050 series is designed to meet the electrical requirements of modern systems, though technicians should verify specific spark-ignition safety standards for the overall cabinet enclosure.

Can I replace a 40 amp unit with this 50 amp model?

Technically, you can use a higher amperage contactor like this 50 amp model to replace a lower-rated unit (e.g., 40 amp), provided the 24V coil voltage and 3-pole configuration align with the original specifications.

What is the difference between AFL and Resistive ratings on this part?

This unit is rated for 40 Amps Full Load (AFL) for inductive motor loads and 50 Amps for resistive heating loads, ensuring safe operation within nameplate tolerances.
