Eaton 9-1989-1 Relay Magnet Coil 120V Type M

Product Description

The EATON 9-1989-1 is a replacement magnet coil designed for use in Type M multipole relays. This coil operates at 110 VAC at 50 Hz or 120 VAC at 60 Hz, making it compatible with both domestic 60 Hz electrical systems and international 50 Hz installations. The magnet coil is the electromagnetic component responsible for actuating the relay armature and closing the contact assembly when energized. It is a direct replacement component installed by licensed electricians and industrial maintenance technicians during relay service or coil burnout repair on NEMA-rated control relay assemblies.

This coil is used in control relay applications across commercial and industrial electrical systems. It fits the Type M multipole relay platform, which is commonly found in motor control centers, machine control panels, and industrial automation equipment. The D26 coil designation identifies the specific coil frame and voltage class within the Type M relay series. Installations are typical in panels governed by NEC requirements for motor branch circuit and control wiring.

Key Features

• Dual-frequency rated: 110 VAC at 50 Hz and 120 VAC at 60 Hz
• Designed specifically for Type M multipole relay assemblies
• D26 coil frame designation for direct OEM-style replacement
• NEMA Control Relay category for industrial and commercial panel applications
• Enables field coil replacement without full relay assembly swap

Compatibility

Designed as a replacement magnet coil for EATON Type M multipole relay assemblies as specified in the product documentation. Verify coil frame designation and voltage rating against the existing relay assembly before installation.

Installation Notes

Magnet coil replacement on control relays should be performed by a qualified electrician with the panel de-energized and locked out per NFPA 70E lockout/tagout procedures. Confirm the supply voltage and frequency match the coil rating before energizing. Inspect the relay armature face and coil mounting surfaces for wear or debris before seating the replacement coil. Consult the relay manufacturer documentation for coil removal and reassembly sequence specific to the Type M frame.
