■
Overview
• Small distribution boards for modular installation devices with
mounting depths of 55 mm and from 55 mm to 70 mm
• Modular width 1 MW
r
18 mm
• Cut-out height in the cover for shock protection: 45 mm
■
Benefits
• Simple cable entry due to the plug-in and latching sliding
flange
• Fast wiring through N/PE plug-in terminals (in flush mounting
and hollow-wall distribution boards for modular installation de-
vices up to a mounting depth or 70 mm) and tried and test
strain-relief clamping terminals (remaining small distribution
boards of the SIMBOX 63 range)
• Convenient cable routing thanks to the wiring space that has
been expanded to 12 mm in versions of the modular devices
with a mounting depth of up to 70 mm
• The modern design of the steel sheet door and its handle en-
able fast concealed lock installation
• High mechanical strength due to
- raised masking frame,
- double-layer wall-recessed boxes made of impact-resistant
plastic and
- electrogalvanized steel sheet doors and masking frames
with powder coating
• Masking frames provide flush mounting flexibility of up to
22 mm
• Standard mounting rails can be fitted in the wall-recessed box
before installation
■
Application
Small distribution boards are suitable as sub-distribution boards
or floor panel boards for all applications in electrical building in-
stallations. Due to their small mounting depth, they can be in-
stalled close to the respective load center in residential and non-
residential buildings, as well as in schools, commercial buildings
and shops.

Design
Versions
Small distribution boards for flush-mounting, hollow-wall, sur-
face-mounting and hood-type distribution boards (without door)
are available in 1 to 4-tier versions; hood-type distribution
boards with doors are only available in the 1 to 3-tier version.
Equipment
The distribution boards can be equipped with modular installa-
tion devices, such as MCBs and RCCBs, up to a mounting depth
of 55 mm or 70 mm with mountings for snapping onto the 35 mm
x 7.5 mm standard mounting rails according to EN 60715.
Each tier can be fitted with devices up to 12 modular widths. For
the 3 and 4-tier versions, the upper and lower tier can be extend-
ed to 13 modular widths by cutting out the knockouts in the
shock protection cover.
