Why Choose the ABB MBM311 Mounting Plate Expansion 3PW?
The ABB MBM311 is a CombiLine mounting plate expansion module designed to provide a flexible equipment mounting area within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041709R9999, it forms part of the ABB DESUJ Sub Distribution product group and is intended for professional sub-distribution and panel-building applications.
The MBM311 combines a robust 2 mm sheet-steel mounting plate with a wide 3-panel-width (3PW) format. The module has a nominal height of 150 mm and width of 750 mm, provides 36 space units and is intended for cabinets from 200 mm depth.
Unlike fixed-depth MBM...K versions, the MBM311 mounting plate can be continuously adjusted in depth using the ABB ZW59P2 deep-angle accessory. This provides useful installation flexibility for components with different mounting depths, while its closed cover creates a clean finished cabinet front. A compatible mounting frame or mounting profile is ordered separately.
Key Advantages
- Wide 3-panel-width (3PW) mounting area for electrical equipment.
- Durable 2 mm sheet-steel mounting plate.

Flexible Equipment Mounting with Adjustable Depth
Mounting plate modules provide a versatile alternative to fixed DIN-rail layouts when electrical equipment requires direct mounting to a flat supporting surface. The 2 mm sheet-steel plate of the ABB MBM311 provides a robust base for compatible control, distribution and ancillary electrical components, while the wide 3PW format offers approximately 688 mm of usable equipment width.
The MBM311 also supports variable depth positioning using the ABB ZW59P2 deep-angle accessory, providing approximately 103–158 mm of usable mounting depth. This allows the mounting surface to be positioned to suit equipment dimensions and cabinet layout requirements, making the module particularly useful for customised CombiLine assemblies.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- Direct mounting of electrical and control components.
- Electrical sub-distribution assemblies.
- Industrial and commercial switchboards.
- Custom equipment mounting within distribution panels.
- Professional panel-building and system integration projects.
