Eaton 9-1891-1 Replacement Coil
This Eaton 9-1891-1 replacement coil is designed for NEMA Size 4 and 5 contactors in the Series Freedom range. It suits maintenance engineers and electricians who need a direct 120/110V AC coil replacement for existing motor control equipment.
Installation and common issues
Installation requires isolating the supply, removing the contactor cover and swapping the coil assembly. A frequent error is fitting the coil without confirming the contactor frame matches NEMA Size 4 or 5, which prevents correct mechanical engagement.
Compatibility checks before ordering
Verify that the contactor is a Series Freedom unit with NEMA Size 4 or 5 designation. Confirm the control circuit operates at 120/110V AC and 50/60 Hz, and that the coil power rating of 1,040 VA matches the application requirements.

Questions about this item
How can I verify the 120VAC coil is operating correctly after installation?
Energise the contactor at 120VAC 50/60Hz and confirm the contacts close cleanly; the coil should draw approximately 1,040VA during pull-in.
What comes with the 9-1891-1 replacement coil and what must be sourced separately?
The package contains the coil only; mounting hardware, terminal lugs and any series Freedom contactor base are not included.
Which NEMA size should I select for my Series Freedom contactor — Size 4 or Size 5?
This single coil fits both NEMA Size 4 and Size 5 Series Freedom contactors, so choose the one that matches your contactor’s nameplate.
