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 flat packed unequipped distribution
boards for surface-mounting distribution boards (delivery in in-
dividual parts for self-assembly), pre-assembled unequipped
distribution boards for surface and flush-mounting distribution
boards, cabinet-height quick-assembly kits for ultra fast equip-
ping and wiring, assembly kits for project-related and individual
assembly - and an extensive range of accessories.
Enclosures
Material: electrogalvanized and powder-coated sheet steel.
Sheet thickness, degree of protection IP43: body 0.75 mm, door 1 mm
Sheet thickness, degree of protection, IP55: body 1 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 that can be mounted with the
ALPHA 400 - DIN wall-mounted distribution boards are Siemens
switching devices with a rated current of 400 A.

Flat pack
The new delivery option for the ALPHA distribution board prod-
uct range offered by Siemens is both a new product and an
innovation.
Flat packed distribution boards are delivered as individual parts
packaged in cardboard boxes for self-assembly.
These boxes contain all essential individual parts, complete with
brief mounting instructions and all mounting accessories.
Only a few manual steps are required to assemble the individual
system components to create wall or floor-mounted distribution
boards of degree of protection IP43.
The only tool required for such assembly is a one-size
screwdriver.
This offers clear advantages and customer benefits: a consider-
able reduction in the delivery volume and storage space
required.
It goes without saying that the distribution boards can also be
delivered as pre-assembled items.
