Why Choose the ABB MB320 Touch Protection Expansion?
The ABB MB320, order code 2CPX041271R9999, is a touch protection expansion module for ABB CombiLine sub-distribution systems. Supplied as a cabinet-installed interior module, it provides closed protective covering for distribution assemblies while allowing the enclosure interior to be expanded using compatible ABB system components.
Designed for professional low-voltage distribution applications, the MB320 combines a robust plastic cover with a practical 90-degree push-turn cover fastener. Its light grey RAL 7035 finish matches compatible ABB distribution equipment, while the 3-field-width format provides substantial coverage for larger panel configurations.
The MB320 has a nominal external size of 750 mm high × 750 mm wide, corresponding to 5 grid units (GU/RE) in height and 3 panel widths (PW/FB) in width. It provides 180 space units (PLE) and is suitable for installations from a cabinet depth of 120 mm. A compatible EDF or WR mounting frame must be ordered separately.

Reliable Touch Protection for Distribution Assemblies
Touch protection modules are used within electrical distribution assemblies to provide a physical barrier between accessible areas and internal electrical components. The ABB MB320 uses a closed plastic cover to support safe, organised construction of compatible low-voltage distribution systems while maintaining access through its practical push-turn fastening arrangement.
As part of the ABB CombiLine system, the MB320 is designed for modular interior expansion and can be used with compatible EDF or WR mounting structures. Its 750 mm × 750 mm format and 180 PLE capacity make it particularly suitable for larger distribution panel sections where broad protective coverage is required.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial sub-distribution systems.
- ABB CombiLine panel assemblies.
- Electrical control and distribution cabinets.
- Interior panel expansion using EDF or WR mounting frames.
- Applications requiring closed touch protection over electrical equipment.
