Abstract
A coupling element for electrically coupling a lateral connecting portion of a first laminated busbar to a lateral connecting portion of a second laminated busbar, the coupling element having a base body that includes a sandwich of conducting layers of sheet metal and intermediate insulating layers arranged in between the conducting layers for electrically insulating the conducting layers from each other. Each of the conducting layers includes a first layer section that is associated to the lateral connecting portion of the first busbar and a second layer section that is associated to the connecting portion of the second busbar. The first and second layer sections are electrically insulated from each other by an insulating element and each of the first layer sections includes a first circuit breaker connecting terminal that is adapted to be electrically connected to an input terminal of a circuit breaker.
