About the MMII-PD-1-2-MOD600-120

The MMII-PD-1-2-MOD600-120 is a Motor Manager II relay produced by General Electric Multilin. The relay is rated with a 120 VAC supply voltage. Its maximum contact rating is 250 VAC. The base unit MM2 product family is typically in stock here at AX Control in several iterations.

The MMII-PD-1-2-MOD600-120 is designed to offer control functions and motor protection in a single package. This unit offers intelligent motor controls and protective relaying with significant savings over discrete devices that are typically used in a low voltage MCC (motor control center.)

The unit is designed to display ground current and phase current, analog input, thermal capacity, power, and other system parameters. It offers up information like necessary maintenance information, pre-trip values, and trip records. The unit offers protection and control through six fixed and ten programmable inputs and two contactors and two programmable outputs.

General Electric Multilin’s MMII-PD-1-2-MOD600-120 has an LCD display that allows local interfacing and access to information. The RS485 Modbus interface also allows remote connections at a transfer rate of 1200-19,200 baud. The front panel also includes nine LED indicators (running, stopped, tripped, alarm, fault, contactor a and b, aux 1 and 2), as well as input keys.

This unit is designed for panel mounting (PD) with a display. Manuals and user guides originally provided by GE can help you with proper handling, wiring, and installation. This document would have arrived with your OEM purchase. If you no longer have your original copy, AX Control may be able to help. We keep a full library of manuals for GE motor controllers and other equipment.

Frequently Asked Questions about MMII-PD-1-2-MOD600-120

How does EnerVista MMII enable better management and protection for the MMII-PD-1-2-MOD600-120?

EnerVista provides a user interface with enhanced efficiency, especially when compared to using the keypad and LCD for settings management. EnerVista also provides a suite of tools that help optimize motor management and protection, such as the EnerVista integrator, which assists in getting the motor management device up and running as quickly as possible. It also automatically updates manuals, brochures, and datasheets to ensure the user has the most up to date information for their relay. EnerVista also allows the trending, graphing, and exporting of data that can then be used to increase system efficiency.

How easy is integrating the relay into a new/existing motor system? What is the process for mounting the device?

The MMII-PD-1-2-MOD600-120 unit is quite small, so the unit is easily installed on a seven inch panel cutout. The user can use the #8-32 or #6 x ½ mounting screws to affix the device to the panel. The instructions are slightly different for the version with a display and the version without, so users should reference their user manual when initiating the mounting process.
