Why Choose the ABB MM314 Mounting Plate Expansion 3PW?
The ABB MM314 is a factory-assembled CombiLine mounting plate expansion module designed for installing electrical equipment within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041253R9999, it combines a substantial steel mounting area with the modular dimensions required for coordinated sub-distribution panel construction.
The MM314 is configured for 3 panel widths (3 PW) with a field width of 750 mm and a module height of 600 mm. Its 4 RE configuration provides 144 space units, while the mounting plate itself is manufactured from robust 2 mm sheet steel to provide a secure installation surface for electrical components.
The mounting plate can be continuously adjusted in depth using deep-mounting brackets, providing a usable depth range of 103–158 mm. A usable equipment mounting area of approximately 688 mm wide × 566 mm high makes the MM314 suitable for larger components and customised panel layouts. Closed plastic covers finished in RAL 7035 complete the assembly, which is suitable for compatible cabinets from 200 mm depth.

Reliable Equipment Mounting for Distribution Systems
Mounting plate modules provide a versatile internal installation surface for electrical components that cannot be accommodated on standard modular DIN rails. The ABB MM314 uses a rigid 2 mm sheet-steel plate with a substantial usable mounting area, allowing panel builders to position compatible control, protection and distribution equipment according to the requirements of the assembly.
The continuously adjustable mounting depth allows equipment positioning to be adapted to component dimensions and cabinet layout requirements. As part of the ABB CombiLine system, the MM314 provides a coordinated 3 PW solution for larger commercial and industrial distribution assemblies where flexible equipment mounting and efficient use of cabinet space are important.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- Mounting of electrical protection and control equipment.
- Custom equipment layouts within electrical cabinets.
- Commercial building electrical distribution systems.
- Industrial distribution and control panels.
- Panel-building applications requiring a large steel mounting surface.
