ALPHA distribution boards
Our ALPHA distribution boards and components are series pro-
duced. Regular type tests and routine tests, by both internal and
external testing laboratories, ensure uniform quality and the
highest technical standards. Our product spectrum ranges from
small distribution boards (up to 63 A) through to distribution
boards with 630 A busbar load capacity.
The ALPHA distribution boards comply with standards
EN 60439-1 (VDE 0660-500) and EN 60439-3 (VDE 0660-504).
The respective type tests are performed according to Table 7,
sections 8.2.1 ... 8.2.7 or 8.2.15 of the aforementioned regula-
tions.
