Eaton Cutler-Hammer C25DND230B Contactor

The Eaton Cutler-Hammer C25DND230B is a heavy-duty 2-pole definite purpose contactor designed for high-cycle applications in HVACR and industrial machinery. Engineered with a 30-amp inductive rating and a 40-amp resistive rating, this component features a 208/240Vac 50/60Hz coil suitable for standard commercial voltage configurations. The open type enclosure architecture allows for maximum heat dissipation, while the integrated metal mounting plate ensures a rigid, vibration-resistant installation in control panels. This non-reversing contactor is a drop-in replacement for many OEM motor control circuits, providing reliable switching for compressors, fans, and resistance heating elements. With screw/pressure plate terminals and quick-connect lugs, field wiring is streamlined for fast service calls. This C25 frame size model is recognized for its durability in demanding environments where consistent load switching is critical for system uptime.

• High-Amperage Capacity: Rated for 30A Full Load Amps (FLA) and 150/120A Locked Rotor Amps (LRA) at 240/480V.
• Versatile Coil Voltage: The 208-240V AC coil operates efficiently across both 50Hz and 60Hz frequencies.
• Universal Compatibility: Standard Eaton C25 series footprint facilitates straightforward replacement of failing definite purpose contactors.
• Robust Construction: Features silver cadmium oxide contacts for arc resistance and extended mechanical life.
• Compact Design: Ideal for tight wiring gutters and control boxes without sacrificing electrical clearance.

Is the C25DND230B compatible with 208V and 240V systems?
Yes, the dual-voltage coil is specifically designed to pull in and hold reliably on both 208V and 240V AC power supplies without overheating or chatter.

What is the difference between a 2-pole and a 1-pole contactor in this application?
A 2-pole contactor breaks both "hot" legs of a single-phase circuit, ensuring the load is fully de-energized, whereas a 1-pole contactor leaves one leg energized to the ground.

Can I use this contactor for a 1.5 HP motor?
Yes, this 30A contactor is rated for HVAC motor loads typically up to 2 HP at 240V, making it an excellent choice for a wide range of condenser units and blowers.
