Eaton Cutler-Hammer C25DNF330A Contactor

The Eaton Cutler-Hammer C25DNF330A is a 3-pole, 30-amp definite purpose contactor engineered for demanding HVACR and industrial motor control applications. Operating on a 110/120Vac 50/60Hz coil voltage, this non-reversing unit features an open type enclosure with a robust metal mounting plate, ensuring stable installation in control panels. Designed to handle inductive loads up to 30 FLA and resistive loads up to 40 amps, the C25DNF330A utilizes silver cadmium oxide contacts to provide superior conductivity and arc resistance. This Eaton C25 contactor is a direct replacement for many OEM motor starters and is compatible with standard quick-connect terminals or screw/pressure plate connectors. Its compact frame and 3-pole contactor configuration make it a reliable choice for 3-phase motor control, commercial refrigeration systems, and high-capacity air conditioning units where durable switching performance is professional-grade requirement.

• Universal Compatibility: Fits standard mounting footprints for seamless replacement of legacy Eaton C25 series models and competitive brands.
• Enhanced Durability: Metal mounting plate reduces vibration stress, extending the mechanical life of the 30 amp contactor.
• Optimal Performance: 120V coil is optimized for standard control circuits, providing reliable pull-in even during minor voltage fluctuations.
• Efficient Termination: Box lugs and quick-connect terminals allow for fast field wiring and secure HVAC electrical component integration.

Is this contactor suitable for 208/240V control circuits?
No, this specific model is rated for a 110/120Vac coil. Applying 240V to the coil will result in immediate failure. Always verify your control transformer output before installation.

Can the C25DNF330A be used for resistive heating loads?
Yes, while rated at 30 amps for inductive loads (FLA), it is typically rated for up to 40 amps for resistive (non-inductive) loads, making it versatile for strip heaters and ovens.

Does this unit include auxiliary contacts?
The standard C25DNF330A comes as an open-frame unit without factory-installed auxiliaries, though its side-mount design allows for the field addition of snap-on auxiliary blocks if needed.
