Control Center Minimizes Arc Flash Hazard
ABB’s Low Voltage Products division has released the MNS-MCC Low Voltage Motor Control Center, described as the first of its kind designed to address the causes of arc flash incidents while pro-viding equipment and personnel protec-tion. In developing the MNS-MCC, ABB said it took the primary features of a globally proven IEC product and incor-porated them into a unique, comprehen-sive low-voltage motor control center that meets UL 845, CSA C22.2 and IBC-2006 standards. To achieve the greatest possible flexibility and mini-mize downtime, the MNS-MCC offers plug-in type, withdrawable type, and full height unit technology, with up to 4,000 A horizontal bus and 1,600 A vertical bus. Its innovative design is available in a variety of unit types, including starters, soft starters, variable frequency drives, and mains and feeder breakers. According to the vendor, the MNS-MCC provides operators the highest degree of safety and efficiency during normal operation and while performing mainte-nance. No other MCC allows the opera-tor to remove a unit with the door closed, with no tools, without discon-necting any wires. This easy removal capability encourages work to be per-formed outside the arc flash boundary.
