Benefits
• Flat pack delivery option (assembly kit for self-assembly, i.e.,
the quick-assembly kits and assembly kits can be mounted
directly onto the platform) or delivery as pre-assembled un-
equipped distribution board
• Easy planning thanks to modular design
• Ample wiring space behind the standard mounting rail
• Comprehensive range of cabinet-high and frequently used
quick-assembly kits and assembly kits for individual and
project-related assembly

modules with quick-acting locks
• Short mounting times thanks to quick-assembly kits
• System concept according to DIN, EN and VDE regulations
• Solid sheet-steel enclosure
• Degree of protection: surface-mounting version: IP43 with
door, IP55 with door; flush-mounting version: IP31 with door
and integrated masking frame
• Safety class 1 (protective conductor connection) or safety
class 2 (total insulation)
• High-quality surface finish: distribution boards made of elec-
trogalvanized and powder-coated sheet steel, system compo-
nents made of sendzimir-galvanized sheet steel, galvanized
and transparently chromated small components and screws

Application
ALPHA 400 - DIN wall-mounted distribution boards are used for
all applications where an ALPHA 160 - DIN wall-mounted distri-
bution board does not provide sufficient equipping or wiring
space, e.g. in residential, administrative, non-residential,
commercial and industrial buildings.
With a mounting depth of 210 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 400 - DIN wall-mounted distribution board range
comprises wall-mounted distribution boards with up to 9 modu-
lar installation devices, each with 12 MW per mounting width
(250 mm). The standard mounting rail tier spacing is 125 mm or
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) or safety class 2 (total insulation).
The standard degree of protection for surface-mounting distri-
bution boards is IP43 and IP55. The standard degree of protec-
tion for flush-mounting distribution boards is IP31. The rated
current is 400 A.
The modular design of the board enables easy planning,
configuration, calculation, ordering and mounting.
Cabinet-high quick-assembly kits or assembly kits that only re-
quire a one-size screwdriver for assembly are available for all
mountable switching devices and modular installation devices.
