Patent ID: 8829369

Claim:
A spacer for separating two single-pole breaking units, each such unit comprising a unit case, two large panels separated by a width of a unit case, which houses a breaking mechanism between a line-side connection terminal strip and a load-side connection terminal strip, each unit being provided with means for simultaneous driving by a rod, said spacer comprising: a central partition comprising a top end part facing the line-side connection terminal strips, and a separating part whose shape is substantially included in the large panel of the breaking units and comprises a recess for passage of the simultaneous drive rod of the breaking units; securing means enabling orthogonal clamping to said partition; at least one bottom edge substantially perpendicular to the central partition; an element defining a creepage distance, having dimensions which are standardized according to the breaking units, orthogonal to the bottom edge and smaller in thickness than that of the central partition, said thickness measured orthogonally to the large panels, said element being associated with the side of the top end part opposite the separating part, in its thickness, extending on each side of the central partition from the bottom edge to the opposite edge; and a pass-through hole parallel to the element defining the creepage distance in the thickness of the central partition.
