Product images are representative only. Actual product may vary.
The Eaton C25FNF350A is a premium three-pole definite purpose magnetic contactor rated at 50 amps and 600 volts, designed for dependable performance in HVAC, refrigeration, and industrial switching applications. Part of Eaton's industry-leading C25 Series, this unit features quick-connect terminals and box lugs for fast, versatile installation. It carries UL Recognition and CSA Certification for code-compliant use across the U.S. and Canada.
What Is a Magnetic Contactor?
A magnetic contactor is an electrically controlled switching device used to make or break an electrical circuit under load. The C25FNF350A uses a 120V AC coil to energize the electromagnet, which closes the main power contacts and allows current to flow to the connected load. When the coil is de-energized, spring tension opens the contacts to interrupt the circuit. This makes magnetic contactors essential components in motor starters, HVAC systems, and automated control panels.
