Motor Control Center Addresses Arc Flash Incidents

ABB says its newly introduced MNS-MCC motor control center is the first in the industry to address the causes of arc flash incidents while providing superior equipment and personnel protection. The product uniquely allows operators to remove a unit with the door closed, with no tools, and without disconnecting any wires. This easy “bucket removal” encourages work to be performed outside the arc flash boundary.

In developing the MNS-MCC, ABB took the primary features of a globally proven IEC product and incorporated them into a unique, comprehensive low-voltage motor control center that meets UL 845, CSA C22.2, and IBC-2006 standards. To achieve the greatest possible flexibility and minimize factory downtime, the MNS-MCC offers plug-in type, withdrawable-type, and full-height unit technology, with up to 4,000A horizontal bus and 1,600A vertical bus. Its innovative design is available in a variety of unit types, including starters, softstarters, variable frequency drives, and mains and feeder breakers. (
