gree of protection IP43 in the form of flat packs (delivery in indi-
vidual parts for self-assembly, explained in detail in chapter 3),
pre-assembled unequipped distribution boards with degree of
protection IP55, assembly kits for project-related and individual
assembly and an extensive range of accessories.
