Watch this video to see how ABB designed the MNS platform of motor control centers to maximize reliability and minimize maintenance and downtime for today’s process and power-intensive industries.

Downtime can be costly for many businesses such as process manufacturers, data centers, utilities and others that require on a safe, reliable flow of power. These companies depend on reliable low voltage electrical systems. In addition, if something should break, they need systems that are easy to repair so they can get operations back online as quickly as possible.

This video tour will take you through the features, such as withdrawable units and touchproof compartments, that make the ABB MNS platform of motor control centers the most reliable and easiest to maintain on the market today.
