Why Choose the ABB MB319 Touch Protection Expansion 3PW?
The ABB MB319 is a factory-assembled CombiLine touch protection expansion module designed for installation within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041268R9999, it provides a closed protective field for touch protection or for expansion using compatible components from the ABB modular distribution system.
The MB319 is configured for 3 panel widths (3 PW), providing a field width of 750 mm and a module height of 600 mm. Its 4 RE format provides 144 space units, making it suitable for larger internal cabinet fields where a wide protective cover arrangement is required.
Closed plastic covers finished in RAL 7035 protect the internal field and use convenient 90-degree press-and-turn closures. The MB319 is suitable for compatible cabinets from 120 mm depth and can be integrated with ABB EDF or WR mounting-frame arrangements, with the appropriate mounting frame ordered separately.

Reliable Touch Protection for Distribution Systems
Touch protection modules provide a physical barrier between accessible cabinet areas and internal electrical installation spaces. The ABB MB319 combines a closed protective cover arrangement with a wide 3 PW format, helping panel builders create structured and appropriately guarded internal fields within modular low-voltage distribution assemblies.
With its 600 mm module height, 750 mm field width and 144-space-unit format, the MB319 is well suited to larger distribution-board sections. Its CombiLine construction allows coordinated integration with compatible ABB system components and EDF or WR mounting frames for commercial and industrial distribution applications.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- Touch protection within electrical cabinets.
- Protection of large internal distribution-board fields.
- Expansion fields using compatible CombiLine components.
- Commercial building electrical distribution systems.
- Industrial low-voltage distribution panels.
