SIMBOX 63
Introduction
■ Overview
• Small distribution boards for modular installation devices with
device mounting depths up 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 devices
up to a mounting depth of 70 mm) and tried and tested
strain-relief clamping terminals (remaining small distribution
boards of the SIMBOX 63 range)
• Convenient cable routing thanks to the wiring space, which
has been expanded to 12 mm
• The modern design of the steel sheet door and its handle enable
fast concealed lock installation
• High mechanical strength due to
- Increased 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 up to 22 mm flush mounting flexibility
• 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 installations.
Thanks to their compact mounting depth, they can be
installed 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 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 installation
devices, such as MCBs and RCCBs, up to a mounting depth
of 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 extended
to 13 modular widths by cutting out the knockouts in the
shock protection cover.
