Resideo DP2040B1002 Contactor
The Resideo DP2040B1002 is a professional-grade 2-pole definite purpose contactor engineered for demanding HVACR applications, specifically for starting and controlling induction motors. This 40 amp contactor features a 120V AC coil and is designed for high-cycle reliability in commercial and industrial environments. Utilizing silver cadmium oxide contacts, the unit maintains superior conductivity and arc resistance, extending the operational lifespan of the switcher under heavy loads. Its DPST (Double Pole Single Throw) configuration and 1/4" quick connect terminals facilitate streamlined field installation, while the #10-32 combination head screws ensure secure main power connections. With an operating temperature range of -4°F to 149°F, this Resideo HVAC contactor provides consistent performance across extreme mechanical room conditions. The low-profile housing is optimized for tight control panels, offering maximum wiring room and broad compatibility with existing 40A definite purpose switching footprints.
- High-Amperage Capacity: Rated for a 40A inductive full load and 50A-55A resistive load, making it ideal for large compressor and heater circuits.
- Durable Metallurgy: Premium silver cadmium oxide contacts prevent welding and pitting during high-frequency switching cycles.
- Universal Compatibility: Features multiple mounting holes and slots, designed to replace most competitive 2-pole 40A 120V contactors without modification.
- Compact Design: Simplified low-profile architecture allows for increased airflow and cabinet space for easier terminal access.
Common Questions
What is the difference between AFL and resistive ratings on this contactor?
The Resideo DP2040B1002 is rated at 40A AFL (Amps Full Load), which applies to inductive loads like motors and compressors. For resistive loads, such as electric heat banks, it can handle up to 55A.
Can I use this contactor for 208/240V systems?
While the power poles can switch 208/240V, the 120V AC coil requires a 120V control signal to engage. Ensure your transformer or control board output matches the 120V coil specification before installation.
Is this contactor suitable for outdoor condenser units?
Yes, as an HVAC definite purpose contactor, it is rated for typical outdoor operating temperatures (-4°F to 149°F), provided it is housed within a NEMA-rated enclosure or the original equipment control box.
