Eaton C25DNF240A Definite Purpose Contactor 2-Pole 40A 120V AC Coil Non-Reversing

The Eaton C25DNF240A is a commercial-grade, two-pole definite purpose contactor rated at 40 amps with a 110/120V AC, 50/60 Hz coil. Designed for demanding HVACR and industrial motor control applications, this non-reversing contactor delivers reliable switching performance for high-duty-cycle equipment including compressors, pumps, air conditioning units, refrigeration systems, and resistive heating loads.

Part of Eaton's industry-leading C25 series, this compact contactor features an open-type enclosure with a heavy-duty metal mounting plate and box lugs with posidrive setscrew and quick connect terminals, ensuring a secure, low-resistance connection that holds up under vibration and repeated thermal cycling. The magnet housing design limits dust and contaminant ingress, reducing operational noise and extending service life.
