Eaton C25FNE350A – 50 Amp Definite Purpose Contactor | 3-Pole | 120V Coil

The Eaton C25FNE350A is a heavy-duty, three-pole definite purpose contactor rated at 50 amps and engineered for reliable performance in demanding HVAC, refrigeration, lighting, and industrial control applications. Part of Eaton's trusted C25 Series, this contactor is UL Recognized and CSA Certified, making it a code-compliant solution for both commercial and industrial installations.

What Is a Definite Purpose Contactor?

A definite purpose contactor is an electrically operated switching device designed for specific load types — most commonly HVAC/R (heating, ventilation, air conditioning, and refrigeration) equipment. Unlike general-purpose contactors, definite purpose contactors are optimized for low-cycle duty switching of resistive and inductive loads, making them ideal for condensing units, compressors, heat pumps, and lighting panels.
