The 8HP distribution system is a modular system for low-voltage
small distribution boards, control panels and power distribution
boards.
■
Benefits
The optimum design of these high quality materials fulfills all the
demands made on enclosures. This includes:
• Total insulation
• Corrosion resistance
• Mechanical strength
• Simple finish
• Temperature resistance
• No maintenance
• Flame retardant, self-extinguishing
• Halogen-free (thus preventing consequential damage result-
ing from external fire), excludes cable space cover
• Lightweight components.
Total insulation
All enclosure parts and operating mechanisms are designed so
that, if closed during operation, they fulfill the requirements of the
protective measure "Total Insulation" according to DIN VDE 0100
Part 410. All enclosure fixings are on the outside.
■
Application
It is suitable for use in all industrial and commercial areas, in
power plants, large public and private buildings, public utility
companies, as well as office and residential buildings.
The components of the 8HP distribution system comply with the
requirements of type-tested low-voltage switchgear assemblies
(TTA) according to EN 60439-1/DIN VDE 0660 Part 500. The en-
closure complies with the protective measure "Total Insulation"
according to DIN VDE 0100.
