Product Description

This module is the MMII-PD-1-2-120, a model of the Motor Manager II series from General Electric Multilin. These units were produced and developed initially by the industrial automation branch of GE, and have long since been out of production. Fortunately, our technicians at AX Control have skillfully refurbished and optimized our inventory to run as efficiently and smoothly as possible.

The MMII-PD-1-2-120 unit is a motor control center. This module combines several comprehensive functions regarding control and motor protection. This device is built with a compact frame but is still outfitted with the capacity to provide advanced protective relaying at a lower cost than similar, less effective models.

This unit, as well as the other models in the Motor Manager II series, is built to handle numerous tasks and react quickly if any events occur. It can protect from a possible overload or an unbalanced phasing. Should a contactor fail or a rotor becomes locked and/or stalled, then this unit can detect and run routines to get it under control. The unit is also outfitted with a hot winding thermistor circuit. If the model is receiving a power intake that is below the nominal threshold, this unit is equipped with an undervoltage auto restart.

The display capabilities of this model enable it to show phase and ground current, thermal capacity, and energy levels. These parameters can be viewed through the LCD or through Multilin's EnerVista MMII software program.

Once purchased, the MMII-PD-1-2-120 model, as well as the rest of AX Control’s wide inventory, is covered by our extensive, protective warranty for up to 3 years (depending on the product classification).
