Why Choose the ABB MM311 Mounting Plate Expansion 3PW?
The ABB MM311 is a CombiLine mounting plate expansion module designed to provide a wide, structured equipment mounting area within professional low-voltage distribution cabinets. Supplied under ABB order code 2CPX041244R9999, the MM311 is a mounted cabinet module with a 3-field-width / 750 mm configuration for accommodating directly mounted electrical equipment.
The MM311 uses a robust 2 mm sheet-steel mounting plate and provides a usable equipment width of 688 mm and usable height of 116 mm. The mounting plate can be continuously adjusted in depth using deep-angle pieces, providing a usable depth range of 103–158 mm for flexible equipment positioning.
With a module height of 1 RE / 150 mm, a field width of 3 FB / 750 mm and 36 space units, the MM311 provides substantial horizontal mounting capacity while using only one raster unit vertically. Closed plastic covers with 90-degree push-turn fasteners and a RAL 7035 finish complete the module, which is suitable for cabinets from 200 mm depth.

Flexible Equipment Mounting for Distribution Cabinets
Mounting plate expansion modules such as the ABB MM311 provide a dedicated surface for electrical devices and accessories that require direct cabinet mounting rather than conventional modular DIN-rail installation. The broad sheet-steel mounting surface gives panel builders flexibility when positioning equipment while maintaining an organised and accessible distribution assembly.
The MM311 combines a wide three-field format with continuously adjustable mounting depth, allowing equipment positioning to be adapted to the requirements of the installation. As part of the ABB CombiLine interior expansion system, it integrates into compatible cabinet arrangements using an EDF or WR mounting frame, which must be ordered separately.
Typical Applications
- Low-voltage electrical distribution cabinets.
- ABB CombiLine interior expansion systems.
- Sub-distribution boards and switchgear assemblies.
- Direct mounting of electrical devices and accessories.
- Commercial and industrial electrical installations.
- Panel building and distribution cabinet interior expansion.
