Control Center Diagnoses Arc Flash Incidents
The ABB has released the MNS-MCC Low Voltage Motor Control Center, designed to address the causes of arc flash incidents while providing superior equipment and personnel protection. 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 4000A horizontal bus and 1600A vertical bus. Its design is available in a variety of unit types, including starters, soft starters, variable frequency drives, and mains and feeder breakers.
The MNS-MCC provides operators the highest degree of safety and efficiency during normal operation and while performing maintenance. No other MCC allows the operator to remove a unit with the door closed, with no tools, without disconnecting any wires. This easy bucket removal encourages work to be performed outside the arc flash boundary.
The new motor control center is targeted for markets with UL-845, CSA or NOM requirements, and in applications where Arc Flash is a concern, including: substations; critical power facilities such as hospitals and data centers; oil rigs; chemical plants; mining facilities; steel mills; paper mills; and water and wastewater facilities.
