Eaton Cutler-Hammer C25FNF350A Contactor

The Eaton Cutler-Hammer C25FNF350A is a commercial-grade 3-pole definite purpose contactor engineered for demanding HVACR and industrial applications. Designed for high-duty cycles, this 50-amp contactor features an open-type enclosure and a robust metal mounting plate for secure installation in control panels. The 110/120Vac 50/60Hz coil voltage ensures compatibility with standard control circuits, while the non-reversing design provides a compact footprint for space-constrained layouts. This component is optimized for inductive load management, specifically for motor-driven equipment like compressors and fan motors where reliable switching is critical. Utilizing box lugs with posh-to-connect terminals, the C25FNF350A facilitates a secure electrical connection, minimizing resistance and heat buildup. Whether you are performing a field replacement or a new system buildup, this DP contactor meets UL and CSA standards for technical performance in harsh environments.

• 50A Full Load Amps (FLA) rating allows for high-amperage switching in multi-phase mechanical systems.
• Silver cadmium oxide contacts provide superior conductivity and prevent welding under high-inrush startup currents.
• Standardized mounting footprint ensures easy drop-in replacement for existing Eaton or competitor 50-amp 3-pole units.
• Dual-frequency coil (50/60Hz) allows for versatile operation across different power grid standards without performance degradation.

What is the locked rotor amp (LRA) rating for this 50-amp contactor?
The C25FNF350A is typically rated for 300 LRA at 240V, making it suitable for high-torque compressor starts in large HVAC units.

Can this contactor be used for resistance heating loads?
Yes, while focused on inductive loads, it handles resistive loads (NEMA heating) up to 65 amps, provided the voltage remains within the specified range.

Is this contactor field-serviceable?
While the coil can be accessed, we recommend replacing the entire unit if the contacts show significant pitting to ensure total system reliability.
