Square D 9998DA3V02 Contactor Replacement Coil

Product Description

The SQUARE D 9998DA3V02 is a replacement contactor coil designed to restore proper operation to 8910DPA series contactors. The coil generates the electromagnetic field that pulls in the contactor armature, closing the power contacts when the control circuit is energized. This type of coil is a common wear component in motor control and load-switching applications. Electricians and HVAC technicians replace these coils when a contactor fails to pull in or chatter is traced back to a failed coil rather than the full contactor assembly. The part weighs 0.4 pounds and measures 3.6 inches in length, 2.6 inches in width, and 1.9 inches in height.

Replacement coils like the 9998DA3V02 are used in commercial and industrial electrical panels, motor control centers, and HVAC equipment where 8910DPA contactors are installed. Typical applications include compressor circuits, fan motor circuits, and general-purpose load switching. This coil allows a technician to service the contactor in the field without replacing the entire device, reducing parts cost and downtime on a repair call.

Installation Notes

Coil replacement should be performed by a licensed electrician or qualified HVAC technician. De-energize and lock out the panel or disconnect supplying the contactor before beginning work, following NFPA 70E arc flash and lockout/tagout procedures. Verify the replacement coil voltage rating matches the control circuit voltage before installing. Inspect the contactor frame and contacts for additional wear while the coil is removed.
