Eaton C25DNF340B (42CF35AG) Contactor

The Eaton C25DNF340B is a heavy-duty 3-pole definite purpose contactor engineered for high-cycle applications in HVACR and industrial machinery. Rated for 40 amps inductive and 50 amps resistive, this contactor features a 208/240V AC coil, making it a direct technical match for the 42CF35AG. Designed with a compact D-Frame footprint, it utilizes box lugs and quick-connect terminals to ensure secure wire terminations and reduced installation time. The silver cadmium oxide contacts are specifically built to minimize arcing and resist welding under high-inrush loads common in compressor contactor and motor starter applications. Whether managing a three-phase condenser or a large electric heat load, the Eaton C25 series provides reliable switching performance and mechanical durability that meets or exceeds OEM requirements for definite purpose control systems.

• Universal Compatibility: Exact specifications as the 42CF35AG, ensuring a drop-in fit for various HVAC units and industrial equipment.
• High Load Capacity: Rated for 40A FLA (Full Load Amps) and 240V coil operation, suitable for demanding 3-phase power circuits.
• Durable Construction: Features a dust-resistant open enclosure design and high-grade contact materials for extended cycle life.
• Flexible Termination: Equipped with both box lugs and 1/4-inch quick-connect terminals for versatile field wiring.

Is the Eaton C25DNF340B compatible with 208V and 240V systems?
Yes, the coil is rated for both 208V and 240V AC, allowing it to function across standard American commercial and residential voltage ranges.

Can this contactor replace a 2-pole unit?
While a 3-pole contactor can technically switch a 2-pole load, the frame size and mounting footprint should be verified to ensure it fits the existing control box.

What is the difference between this and the 42CF35AG?
Technically, they are equivalent. The Eaton C25DNF340B provides the same electrical ratings, pole configuration, and frame size as the 42CF35AG cross-reference.
