Why Choose the ABB MBB320 Touch Protection Expansion 3PW?
The ABB MBB320 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 large closed protective section for covering internal equipment or expanding compatible distribution cabinet installations.
Supplied as an unassembled kit, the MBB320 incorporates closed plastic covers finished in light grey RAL 7035. The covers use practical 90-degree push-turn fasteners, providing an organised protective barrier across the designated internal cabinet area.
Configured for 3 panel widths (3PW), the MBB320 measures 750 × 750 × 120 mm and provides 180 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 MBB320 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 3PW width, 5 RE height and 180-space capacity, the MBB320 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.
- Large modular sub-distribution assemblies.
