Resideo DPL1030A5014 Contactor

The Resideo DPL1030A5014 Contactor is a heavy-duty 1-pole definite purpose contactor engineered for high-cycle reliability in residential and commercial 24V HVAC systems. As a direct OEM replacement contactor, this unit features silver cadmium oxide contacts to prevent welding and pitting, ensuring consistent conductivity across its 30-amp inductive load rating. This model is explicitly designed to meet ARI-780 standards and is fully compatible with modern A2L refrigerants, making it a versatile choice for updated equipment. The low-profile housing includes a shunt and 1/4" quick connect terminals to streamline field wiring in tight enclosures. Whether you are replacing a MARS 61320 or DP1030A5014, this SPST relay offers a universal mounting plate to reduce downtime during service calls. Rated for mechanical life up to 500,000 cycles, it provides the robust switching performance required for demanding compressor and fan motor applications.

Technical Benefits:

• Broad Compatibility: Direct cross-reference for MARS 61320, Eaton C301NU10, and DP1030A5014/U.
• A2L Ready: Engineered for safe operation with the latest low-GWP mildly flammable refrigerants.
• Enhanced Durability: Silver cadmium oxide contacts provide superior arc resistance and thermal stability.
• Space-Efficient Design: Low-profile footprint increases available wiring room within the air handler or condenser cabinet.
• Standardized Ratings: Meets UL File E220475 and E59779 specifications for 200,000 electrical cycles.

Common Questions:

Is the DPL1030A5014 compatible with 208/230V control circuits?
No, this specific model features a 24Vac coil. Always verify your transformer output before installation to avoid coil burnout.

Can this be used to replace a 2-pole contactor?
This is a 1-pole contactor with a shunt. It breaks only one side of the line. If your application requires breaking both hot legs for safety or code compliance, a 2-pole model is necessary.

What are the lug torque requirements for 30A service?
When using the box lugs, ensure connections are torqued to manufacturer specifications to prevent high-resistance heating at the terminal block.
