Why Choose the ABB MBB220 Touch Protection Expansion 2PW?
The ABB MBB220 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 or expanding compatible distribution cabinet installations.
Supplied as an unassembled kit, the MBB220 incorporates closed plastic covers finished in light grey RAL 7035. The covers use practical 90-degree push-turn fasteners, providing a structured protective barrier over the designated internal cabinet area.
Configured for 2 panel widths (2PW), the MBB220 measures 750 × 500 × 120 mm and provides 120 space units. It corresponds to 5 grid units (RE) and is suitable for 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 MBB220 provide a physical barrier across designated internal areas of an electrical distribution assembly. The closed cover construction helps prevent unintended contact with internal equipment while maintaining an orderly cabinet layout and supporting controlled access during installation and servicing.
The ABB CombiLine modular system enables panel builders to combine compatible internal installation modules according to the required cabinet configuration. With its 2PW width, 5 RE height and 120-space capacity, the MBB220 provides a substantial protected section for larger low-voltage sub-distribution assemblies.
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.
