Dual Busbar Architecture — Horizontal & Vertical
The BlokSet 5000 separates its busbar system into two independent layers. The horizontal main busbar runs along the top of the switchgear lineup and distributes power from the incoming feeder to all functional units. The vertical distribution busbar runs down each individual cubicle, feeding the outgoing breakers inside that compartment. This dual-layer design allows the main busbar to be rated for the full system current while the vertical busbar can be sized per cubicle, reducing copper usage and optimizing heat dissipation.

The horizontal main busbar is available in five standard withstand current grades: 42/50/65/85/100 kA for 1-second short-time withstand, corresponding to peak withstand currents of 88/105/143/187/220 kA. The vertical distribution busbar is available in three grades: 30/50/65 kA with corresponding peak values of 63/105/143 kA. The grade selection depends on the upstream transformer capacity and the required protection coordination.
