Abstract
A passive arc control system for a motor control centerincludes an arc attenuating box having sides separating adjacent vertical bus bar phases, providing a physical barrier to arc flash energy. The box is open at its top and bottom forming a chimney. A shutter assembly for each box includes an insulator capon a free end of the bus bar and an independently moveable, box-shaped shutterthat slides along the bus bar away from the insulator cap, when a device is connected to the bus bar. The shutter has an openingthrough which the bus bar passes when the device is connected to the bus bar and an openingaligned with the box's chimney. The arc control system provides a high degree of arc protection for personnel working around open motor control centers and is highly modular and easy to construct.
