Overview: Square D MCC Model History

Square D (now Schneider Electric) has manufactured Motor Control Centers under the "Model" designation for decades. The Model 5 was the predecessor to the Model 6, and while both are still found in industrial facilities across North America, they have significant differences in design, compatibility, and secondary market value.

How to Identify Which Model You Have

The easiest way to identify your Square D MCC model is to look at the nameplate on the main section. The model designation is typically printed on a label inside the main section door or on the front of the section itself. If you cannot find the nameplate, our buyers can often identify the model from photos of the bucket design and bus system.

Visual Identification Tips

Model 6 buckets have a distinctive rectangular plug-in design with visible bus stab contacts on the back. The bucket door typically has a Square D logo and a catalog number that begins with "8998" or "9998." Model 5 equipment tends to look older and may have a different latch mechanism.
