Overview
System
The modular design of our new Siemens distribution board sys-
tem draws on our long years of experience in the distribution
board sector.
This system has been tailored to meet individual requirements for
distribution board installation.
The system comprises unequipped distribution boards, partially
equipped distribution boards with cabinet-high quick-assembly
kits, cabinet-high quick-assembly kits for modular installation de-
vices for fast equipping and wiring, assembly kits for project-
related and individual assembly as well as an extensive range of
accessories.
Enclosures
Material:
Electrogalvanized and powder-coated sheet steel.
Sheet thickness:
Body 0.75 mm, door 1 mm
Color:
RAL 9016 (traffic white).
Further RAL colors are available on request.
Quick-assembly kits and assembly kits
The assembly kits are made of sendzimir-galvanized sheet steel
and are equipped with molded-plastic covers for a wide range of
equipping options, e.g., for switching devices and modular in-
stallation devices.
The largest switching devices mountable with the ALPHA 160 -
DIN wall-mounted distribution boards are the 3NP40 10 and
3NP40 70 fuse switch disconnectors of size LV HRC 000 and
LV HRC 00 with a rated current of up to 160 A.

Application
ALPHA 160 - DIN wall-mounted distribution boards are used for
all applications for which a small distribution board does not pro-
vide sufficient equipping or wiring space, e.g. in residential, ad-
ministrative, non-residential, commercial and industrial buildings.
Its ultra flat design (depth 140 mm) is an extremely useful addi-
tion to the Siemens distribution board product range.
The distribution board and its components are of modular
design.
With just a few standard components, it is possible to achieve a
wide range of project-related mounting and equipping options.
The ALPHA 160 - DIN wall-mounted distribution board range
comprises wall-mounted distribution boards with up to 7 modular
installation devices with 12 MW per mounting width (250 mm)
each. The standard mounting rail tier spacing is 125 mm or
150 mm. A total of 4 cabinet widths are available, each with an
internal dimension of 250 mm.
The distribution boards can be supplied in safety class 2 (total in-
sulation). The standard degree of protection for surface-mount-
ing distribution boards is IP43 and IP31 for flush-mounting distri-
bution boards. The rated current is 160 A.
The modular design of the board enables easy planning, config-
uration, 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.
