Why Choose the ABB MBB319 Touch Protection Expansion 3PW?
The ABB MBB319 is a modular touch protection expansion designed for ABB CombiLine sub-distribution assemblies. Supplied under ABB order code 2CPX041733R9999, this unassembled interior fitting kit provides closed protective coverage within compatible electrical distribution systems and is part of ABB’s DESUJ Sub Distribution product group.
Designed in a 3PW / three-field-width format, the MBB319 has a module width of 750 mm and a height of 600 mm. Its 4 RE configuration provides 144 space units, making it suitable for protecting a substantial internal area of a modular distribution assembly.
The MBB319 uses closed plastic covers finished in RAL 7035 light grey and incorporates 90-degree press-and-turn closures. It is suitable for cabinets from 120 mm depth and is designed for installation on compatible ABB EDF or WR mounting frames, which are ordered separately.

Reliable Touch Protection for Distribution Assemblies
Touch protection modules provide physical coverage over internal areas of electrical distribution assemblies, helping reduce the risk of unintended contact with installed components. The ABB MBB319 provides a large closed protective area within a three-field-wide CombiLine configuration while maintaining the modular construction principles of the distribution system.
The MBB319 is supplied as an unassembled kit for professional panel construction. Its closed plastic covers, secure press-and-turn closures and compatibility with ABB EDF and WR mounting structures make it suitable for building organised, accessible and protected low-voltage distribution assemblies.
Typical Applications
- ABB CombiLine sub-distribution assemblies.
- Low-voltage electrical distribution boards.
- Touch protection within modular switchgear assemblies.
- Commercial and industrial electrical distribution panels.
- Switchboard and panel-building projects.
- Distribution-board extensions and interior fitting systems.
