8 ABB SACEConstruction and functional characteristicsDistribution busbarsMNS R distribution busbars are avail-able for currents up to 4000 A. Distri-bution busbars, branched directlyfrom main busbars, are vertically in-stalled either on the right or on the leftin the column. They are feeding out-going circuit-breakers, and are con-nected to them by means of rigid orflexible copper busbars, or cables. Inany case, all the connections are suit-ably sized to withstand the thermody-namic stresses of the fault currents.Busbar distribution system with connections to the outgoing circuit-breakers made with copperbusbars and cables.CableconnectionsCopper busbarconnections
