Why Choose the ABB MBM312 Mounting Plate Expansion?
The ABB MBM312 is a CombiLine mounting plate expansion kit designed for installing electrical equipment within ABB low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041712R9999, it belongs to ABB’s DESUJ Sub Distribution product group and provides a versatile internal mounting platform for professional distribution boards and electrical cabinets.
The MBM312 is supplied as an unassembled internal installation module incorporating a robust 2 mm sheet steel mounting plate. It provides a usable equipment area approximately 688 mm wide and 266 mm high, allowing compatible switching, control, connection and other non-DIN-rail equipment to be securely positioned within the enclosure.
With a module height of 300 mm, a 3PW field width of 750 mm and 72 space units, the MBM312 offers substantial mounting capacity. The mounting plate is continuously adjustable in depth from 103–158 mm and is suitable for cabinets from 200 mm depth, while the required ABB EDF or WR mounting frame is ordered separately.

Flexible Equipment Mounting for Distribution Boards
Mounting plate modules provide a versatile installation surface for electrical equipment that cannot be installed directly onto conventional DIN rails. A sheet steel mounting plate allows components to be positioned according to the requirements of the application, helping panel builders create organised and application-specific layouts within distribution assemblies.
The ABB MBM312 combines a robust 2 mm sheet steel mounting plate with a spacious 3PW format and continuously adjustable mounting depth. Its 688 × 266 mm usable equipment area and 72 space units make it suitable for professional CombiLine installations requiring flexible mounting of control, switching, connection or other compatible electrical equipment.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine electrical distribution assemblies.
- Mounting of non-DIN-rail electrical equipment.
- Commercial and industrial distribution cabinets.
- Electrical panel building and cabinet expansion.
- Control, switching and connection equipment installations.
