Square D 9999RR04 Relay Protection Module 110 120V

Product Description

The SQUARE D 9999RR04 is a relay protection module designed to work with Motor Logic overload relays in motor control applications. This module provides coil voltage compatibility at 110 volts and 120 volts, making it suitable for standard North American control circuits. It is a compact, panel-mountable component typically installed by licensed electricians and industrial controls technicians. The 9999RR04 serves as a protective interface between the relay coil and the control circuit, helping to safeguard relay components from voltage spikes and transient conditions during switching operations.

This relay protection module is intended for use with Motor Logic overload relays in motor control centers, combination starters, and industrial control panels. It fits residential, commercial, and light industrial electrical systems where Motor Logic relay assemblies are deployed. The module is a direct accessory component, meaning it mounts to or integrates with an existing Motor Logic overload relay assembly rather than functioning as a standalone device.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the control panel before servicing or replacing any relay protection module. Verify coil voltage rating matches the existing control circuit voltage before installing. Do not force-mount the module; confirm mechanical alignment with the Motor Logic relay assembly before seating.
