Eaton 9-3186 Replacement Coil for C25 Definite Purpose Contactors — 45A, 2/3-Pole
The Eaton 9-3186 is a genuine AC replacement coil for Eaton / Cutler-Hammer Type C25 (Series D1/E1) definite purpose contactors rated 45A (and 50A), in 2- and 3-pole configurations. When a larger contactor still has serviceable contacts but a burned-out or failed coil, replacing just the coil brings it back to full operation at a fraction of the cost of a new contactor — a fast, economical repair for air compressor and HVAC/R motor controls.
Select the coil voltage that matches your control circuit. This coil is the correct replacement for the 45A frame of Eaton's C25 definite purpose contactor line, where the smaller 15–40A devices use the companion 9-3185 coil.

Replacing a failed coil with the correct Eaton 9-3186 coil restores reliable pull-in and dropout on your existing 45A contactor without the expense or downtime of a full contactor replacement. Always confirm the coil voltage stamped on your old coil before ordering.
