The vertical busbar is fitted in the rear part of the standard frame. An intermediate wall with clamps for the control bars and cable holders separates the module compartment. The module compartment is subdivided into closed compartments with insertable module floors. The control plug-in connectors and the tier terminal strip are fitted on the floor of the module. A main contact is fitted on the back as the exit from the module. For small withdrawable units, a cassette, which divides the row into two or four compartments, is used in place of the module floor. The cable connection compartment is closed off with a separate door. The module-, cable- and busbar compartment are compartmentalized among each other in such a way, that internal accidental arcing are limited to the particular compartment in case of inner faults.
