Eaton Cutler-Hammer C25DNF340C Contactor
The Eaton Cutler-Hammer C25DNF340C is a professional-grade 3-pole definite purpose contactor designed for high-demand HVACR applications and industrial motor control. Built to handle a 40 amp inductive load and up to 50 amps resistive, this non-reversing unit is an essential component for technicians servicing large-scale refrigeration, air conditioning units, and motor-driven systems. This model features a 440/480Vac 50/60Hz coil and includes double quick-connect terminals alongside box lug connectors with posidrive setscrews, ensuring secure landings and low-resistance electrical paths under sustained thermal stress.
The open-type enclosure with a factory-integrated metal mounting plate allows for versatile installation within control panels or OEM chassis. Rated for 600V maximum operation, the C25DNF340C is a direct electrical and physical drop-in for legacy 3-pole 40A contactor configurations, including many discontinued Furnas and Siemens series. Its robust bridge architecture and double-break contact design are engineered to mitigate arcing and extend the service life of electrical assemblies in high-cycle environments. Compliance with UL, CSA, and CE standards ensures this contactor meets rigorous safety and performance benchmarks for North American and international electrical codes.
Key Benefits- Enhanced Connectivity: Features both box lugs and side-by-side quick-connect terminals for flexible wiring in the field.
- Universal Mounting: The rugged metal mounting plate provides a stable footprint that aligns with standard 15-50A hole patterns.
- High Thermal Stability: Engineered to operate reliably in ambient temperatures up to 150°F, critical for rooftop HVAC and boiler room environments.
- Industrial Durability: Double-break contacts and heavy-duty 3-pole configuration provide superior arc suppression for inductive motor starts.
What is the difference between inductive and resistive amp ratings?
This contactor is rated for 40 amps inductive (motors/compressors) and 50 amps resistive (electric heating elements). Always size your part based on the specific load type of your application.
Can this contactor replace a 30A model?
Yes, the 40A rating of the C25DNF340C allows it to safely replace 25A or 30A 3-pole contactors, provided the 480Vac coil voltage matches your control circuit.
Is this unit compatible with 50Hz electrical systems?
Yes, the coil is engineered for 50/60Hz dual-frequency operation, making it suitable for global applications or specialized industrial machinery.
