Besides the standard panel blocks, the fully modular switchgear concept offers
the possibility to combine freely configurable panel blocks.
Up to four modules can be combined in one panel block. The position of the individual
modules is free, except for the bus sectionalizer modules.
The width and weight of the switchgear results from the addition of the configured
individual panels.
