Why Choose the ABB MBB117 Touch Protection Expansion 1PW?
The ABB MBB117 is a modular touch protection expansion designed for ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine system and DESUJ Sub Distribution range, it provides a closed protective section for covering internal equipment and expanding compatible cabinet installations.
Supplied as an unassembled kit, the MBB117 uses closed plastic covers finished in light grey RAL 7035. The covers are secured using practical 90-degree push-turn fasteners, helping provide organised touch protection across the designated internal cabinet area.
Configured for 1 panel width (1PW), the MBB117 has a module size of 300 × 250 × 120 mm and provides 24 space units. It corresponds to 2 grid units (RE) and can be installed in cabinets from 120 mm depth using a compatible EDF or WR mounting frame ordered separately.

Touch Protection for Modular Distribution Systems
Touch protection modules such as the ABB MBB117 provide a physical barrier over designated internal areas of an electrical distribution assembly. The closed cover construction helps shield internal components while supporting an orderly cabinet layout and safe access to the distribution system.
The ABB CombiLine system enables panel builders to combine compatible internal installation modules according to the required cabinet configuration. The MBB117 provides a compact one-panel-width protective section that can also be used when expanding a CombiLine assembly with compatible system components.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- Touch protection for internal electrical equipment.
- Commercial and industrial electrical panels.
- Power distribution and control cabinets.
- Modular sub-distribution assembly expansion.
