Abb 15D21G004 Ac Coil Nema Type

Product Description

The ABB 15D21G004 is an AC replacement coil designed for use in NEMA-rated contactors and motor starters. The coil provides the electromagnetic pull-in and hold-in force needed to close contactor contacts when voltage is applied to the control circuit. It is a direct component of the contactor assembly and is typically replaced during routine maintenance or after coil failure caused by voltage spikes, overheating, or age. Licensed electricians and motor control technicians are the primary installers of this component in both commercial and industrial electrical systems.

This AC coil is suited for NEMA-style contactors and motor starters found in commercial and light industrial applications. Typical installations include motor control centers, disconnect panels, and equipment control circuits where NEMA-rated contactors are specified. The coil is installed as a replacement part when the original coil fails, allowing the contactor to be rebuilt rather than fully replaced. Verify the control circuit voltage matches the coil rating before installation.

Key Features

• AC-rated coil designed for NEMA-type contactors and motor starters
• Enables electromagnetic contact closure in the contactor assembly
• Allows field replacement of failed coils without replacing the full contactor
• Direct OEM-style replacement for serviceable NEMA contactor assemblies

Compatibility

Designed as an OEM-style replacement AC coil for NEMA-rated contactors and motor starters. Verify contactor model and control circuit voltage compatibility before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC guidelines. De-energize and lock out the control circuit and main power before removing the existing coil. Confirm the replacement coil voltage rating matches the control circuit voltage before energizing. Handle the coil carefully to avoid damage to the magnet wire windings during installation.
