MCC Option Protects Against Arc Flash Hazards

The Allen-Bradley Centerline 2500 motor control centre ArcShield option helps reduce arc flash hazards and improves protection against internal electrical arcs, providing arc flash protection per IEC/TR 61641:2008 for arcing durations up to 300 msecs. This option provides a pressure relief system that exhausts gases through the top of the enclosure, without front ventilation. In addition, the MCC features automatic shutters that isolate the dis-tribution bus when removing units and insulated power bus closing plates located on the ends of each MCC lineup. In the event of an internal fault, arc containment latches help contain the arc blast.
