Resideo DP1025A5006 Contactor

The Resideo DP1025A5006 is a professional-grade single pole definite purpose contactor engineered for reliable load switching in residential and light commercial HVACR systems. Operating on a 24Vac coil voltage, this 25 Amp contactor features silver cadmium oxide contacts to ensure superior conductivity and minimize arcing under heavy inductive loads. Designed for straightforward field installation, it utilizes 1/4" quick connect terminals and a standard mounting bracket. This SPST contactor is built to withstand rigorous cycles in demanding environments, maintaining an operational temperature range of -4°F to 149°F. For contractors performing maintenance or emergency repairs, the DP1025A5006 serves as a high-performance HVAC replacement contactor that meets OEM specifications for durability. This unit is the direct service replacement for legacy models including 3100A-15Q1, R8242A1057, and R8242A1032, providing a seamless fit for aging air conditioning and refrigeration equipment.

Key Benefits

• Enhanced Contact Life: Silver cadmium oxide contacts provide high arc resistance and reliably handle high-current inductive loads.
• Universal Compatibility: Specifically designed to replace common legacy Resideo and Honeywell contactors without requiring field modifications.
• Broad Temperature Tolerance: Rated for operation from -4°F to 149°F, ensuring stability in outdoor condenser units and unconditioned spaces.
• Simplified Wiring: Industry-standard 1/4" quick connects allow for rapid termination and reduced labor time during service calls.
• Definite Purpose Design: Optimized for motors, compressors, and heating elements where high-frequency switching is required.

Common Questions

What are the compatible replacements for the DP1025A5006?
This unit is the direct technical replacement for the 3100A-15Q1, R8242A1057, and R8242A1032 models. Always verify coil voltage and FLA (Full Load Amps) before installation.

Can this 1-pole contactor be used in a 240V system?
Yes, provided the control circuit is 24Vac. This single-pole contactor breaks one leg of the power supply while the other leg remains continuous, which is standard for many residential condensing units.

What is the importance of silver cadmium oxide contacts in this model?
These contacts are used to prevent "welding" and pitting during high-inrush starts common in HVAC compressors, extending the service life of the electrical component compared to standard alloy contacts.
