Eaton Cutler-Hammer C25DNF240B Contactor
The Eaton Cutler-Hammer C25DNF240B is a heavy-duty 2-pole definite purpose contactor engineered for demanding HVACR and industrial applications. Rated for 40 amps inductive and 50 amps resistive, this non-reversing contactor features a 208/240Vac 60Hz coil (190/220V at 50Hz), making it a standard replacement for high-draw compressors and refrigeration systems. The open type enclosure design is built on a durable metal mounting plate, ensuring a secure fit in existing control panels. This DP contactor utilizes high-grade silver cadmium oxide contacts to provide superior conductivity and arc resistance under heavy cycling. Designed for 40A electrical motor control, it handles locked rotor amps up to 240A at 240V. Whether you are servicing a commercial condenser or an industrial chiller, the C25DNF240B offers the reliability required for 24/7 HVAC duty cycles and definite purpose switching.
Key Benefits
- High Amperage Capacity: Rated for 40A FLA, providing robust performance for HVAC compressor contactor replacements.
- Broad Compatibility: Standard 208/240V coil makes it the best 2-pole contactor for 40 amp service in universal repair scenarios.
- Durable Construction: Features a metal base plate and bind head screw terminals for secure C25DNF240B wiring and vibration resistance.
- Compact Footprint: The open frame design allows for easy integration into tight electrical cabinets without overheating.
Common Questions
How do I wire a 2-pole 40 amp contactor correctly?
Ensure the line and load wires are secured to the primary terminals and the 208/240V control circuit is connected to the coil terminals. Always verify that your system’s voltage matches the 240Vac coil rating to avoid coil burnout.
Can I use a 40 amp contactor to replace a 30 amp unit?
Yes, upgrading to a 40 amp contactor provides a higher safety margin and can extend the service life of the contacts, provided the coil voltage and mounting footprint are compatible.
What is the difference between a definite purpose and a general purpose contactor?
Definite purpose contactors like the C25DNF240B are specifically tuned for the HVACR industry, optimized for cost-effective switching of resistive and inductive motor loads.
