Eaton 9-3185-2 Electromagnetic AC Contactor Coil

The Eaton 9-3185-2 electromagnetic AC contactor coil is the control element that energizes the main contacts in a compatible Eaton contactor. Designed for 208–240 V AC operation and 50/60 Hz input, this coil is configured with a C25 D1 winding and is specifically wound for use with contactors rated at 15 A, 25 A, 30 A, or 40 A. This makes the 9-3185-2 suitable for a range of control-load applications within that current class, translating an electrical signal into a magnetic pull to close the contact set when energized. The 9-3185-2 designation identifies the coil within Eaton's catalog, helping ensure proper matching to the associated contactor hardware so the coil and main contacts operate as a coordinated unit.
