Why Choose the ABB MBB316 Touch Protection Expansion 3PW?
The ABB MBB316 is a CombiLine touch protection expansion module designed to provide a closed protective section within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041724R9999, it forms part of the ABB DESUJ Sub Distribution product group and can be used as touch protection or as an expansion field for compatible system components.
Designed for a 3-panel-width (3PW) configuration, the MBB316 measures 150 × 750 × 120 mm and provides 36 space units. Its wide 750 mm format makes it suitable for creating a substantial closed field across three panel widths while retaining the modular structure of the CombiLine interior expansion system.
The MBB316 is supplied as an unassembled kit with closed plastic covers finished in RAL 7035 and secured by 90-degree press-and-turn fasteners. It can be used from a cabinet depth of 120 mm and is compatible with EDF and WR mounting arrangements, with the required mounting frame ordered separately.

Wide-Format Touch Protection and System Expansion
Touch protection modules provide a closed barrier within low-voltage distribution assemblies where direct access to the area behind the cover is not required. The ABB MBB316 creates a 750 mm-wide closed field across three panel widths, helping maintain an organised and protected cabinet front while preserving the modular structure of the CombiLine system.
The MBB316 can also serve as an expansion field for compatible system components. Its 3PW format, 36 space units and compatibility with EDF and WR mounting systems make it a practical choice for configuring larger customised sub-distribution assemblies.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- Touch protection within electrical distribution assemblies.
- Wide closed protective fields in sub-distribution panels.
- Expansion with compatible ABB system components.
- Commercial and industrial switchboards.
- Professional panel-building and system integration projects.
