trogalvanized and powder-coated sheet steel, system compo-
nents made of sendzimir-galvanized sheet steel, galvanized
and transparently chromated small components and screws

Application
The ALPHA 630 - DIN floor-mounted distribution boards are
used for all applications for which the ALPHA 400 - DIN wall-
mounted distribution boards do not provide sufficient equipping
or wiring space, e.g. in administrative, non-residential, commer-
cial and industrial buildings.
With three available mounting depths of 210 mm, 250 mm and
320 mm, it ideally supplements the Siemens distribution board
product ranges.
The distribution board and its components are of modular de-
sign.
With just a few standard components, it is possible to achieve a
wide range of project-related mounting and equipping options.
The ALPHA 630 - DIN floor-mounted distribution board range
comprises wall-mounted distribution boards with up to 12 mod-
ular installation devices each with 12 MW per mounting width
(250 mm). The standard mounting rail tier spacing is 150 mm.
A total of 5 cabinet mounting widths are available, each with an
internal dimension of 250 mm.
The distribution boards can be supplied in safety class 1 (pro-
tective conductor connection) and safety class 2 (total insula-
tion). The standard degree of protection for floor-mounted distri-
bution boards is IP43 for cabinet depths of 210 mm (flat pack:
delivery as individual parts) and IP55 (pre-assembled un-
equipped distribution boards) for standard cabinet depths of
250 mm and 320 mm. The rated current is 630 A.
40-mm or 60-mm busbar systems with dimensions of up to
30 mm × 10 mm may be installed.
The modular design of the board enables easy planning, config-
uration, calculation, ordering and mounting.
Assembly kits that only require a one-size screwdriver for as-
sembly are available for all mountable switching devices and
modular installation devices.
