Why Choose the ABB MBB317 Touch Protection Expansion?
The ABB MBB317 is a CombiLine touch protection expansion kit designed for use within ABB low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041727R9999, it belongs to ABB’s DESUJ Sub Distribution product group and provides a purpose-designed closed protective covering for professional distribution boards and electrical cabinets.
The MBB317 is supplied as an unassembled internal installation module for touch protection and system expansion. It uses closed plastic covers with 90-degree push-turn fasteners, providing a practical protective barrier over the relevant installation area while maintaining compatibility with the modular ABB CombiLine system.
With a module height of 300 mm, a 3PW field width of 750 mm and 72 space units, the MBB317 provides broad coverage across a three-panel-wide installation field. It is suitable for cabinets from 120 mm depth and can be used with compatible ABB EDF or WR mounting frames, which are ordered separately.

Reliable Touch Protection for Distribution Boards
Touch protection modules provide a physical barrier over internal areas of an electrical distribution assembly, helping create a structured and protected installation while retaining practical access for authorised installation and maintenance work. Closed covers are particularly useful where an installation field does not require front-facing modular device cut-outs.
The ABB MBB317 combines a closed plastic cover design with a spacious 3PW format and 72 space units. Its 300 mm height, 750 mm field width and compatibility with ABB EDF or WR mounting frames make it a practical touch protection solution for professional CombiLine sub-distribution installations.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine electrical distribution assemblies.
- Touch protection for internal electrical installation areas.
- Commercial and industrial distribution cabinets.
- Electrical panel building and cabinet expansion.
- Closed-cover protection within compatible switchboard assemblies.
