Resideo dpl3040b5002 3-pole 120V Definite Purpose Contactor

Product Description

The RESIDEO dpl3040b5002 is a three-pole definite purpose contactor designed for electromagnetic switching in induction motor starting applications. Rated for 110 to 120 volts AC at both 50 Hz and 60 Hz, it delivers a 3PST switch action suited to HVAC and refrigeration load control. The shrouded coil construction protects against moisture and harsh shop environments, while moisture-proof epoxy encapsulation on applicable coil configurations adds durability. This contactor is compliant with A2L refrigerants, making it a current-code-appropriate choice for modern refrigerant systems. Licensed HVAC technicians and refrigeration mechanics are the primary installers.

The dpl3040b5002 is used in residential and light commercial HVAC and refrigeration equipment where three-pole definite purpose switching is required for compressor or motor starting circuits. It is well suited for installations involving A2L refrigerant systems, where component compliance with updated refrigerant safety classifications is required. Multiple mounting holes and slots allow interchangeable installation with most competitive devices, simplifying field retrofits and service replacements. Box lug terminals combined with dual 0.250-inch quick connect terminals support flexible field wiring approaches.
