Eaton C25HNE3120A Definite Purpose Contactor | 120A, 3-Pole, 600VAC, 110/120V Coil

The Eaton C25HNE3120A (also known as the Cutler-Hammer C25HNE3120A) is a heavy-duty, 3-pole definite purpose contactor engineered for demanding motor control applications. Rated at 120 Amps inductive (140A resistive) and 600VAC maximum, this open-type contactor with panel mounting plate delivers dependable switching performance in HVAC, refrigeration, compressor, and industrial motor control systems.

Part of Eaton's C25 Series of definite purpose contactors, the C25HNE3120A is built to handle the toughest load requirements with box lug (posidrive setscrew) terminations for secure, vibration-resistant connections. The coil operates at 110V AC at 50Hz / 120V AC at 60Hz, making it compatible with standard North American control circuits.
