Why Choose the ABB MBG104 Modular Expansion 1PW?
The ABB MBG104, order code 2CPX041665R9999, is an unassembled CombiLine interior expansion module designed for DIN-rail mounted devices in compatible ABB low-voltage distribution cabinets. Part of the DESUJ Sub Distribution product group, it provides a system-matched solution for creating organised modular device rows within professional switchboards and sub-distribution assemblies.
Designed for a 1PW field width of 250 mm, the MBG104 has a module height of 600 mm and provides 48 modular spaces. Four DIN rails provide 12 modular spaces per rail, allowing a substantial number of compatible modular devices to be installed within a compact single-field-width arrangement.
The MBG104 uses 125 mm row spacing and 35 × 15 mm DIN rails with perforations for wire holders. It is designed for installation devices according to DIN 43880, features RAL 7035 plastic covers with device cut-outs and 90-degree press-and-turn closures, and can be used in cabinets from 120 mm depth. A compatible ABB EDF or WR mounting framework must be ordered separately.

High-Capacity DIN-Rail Expansion for ABB CombiLine Cabinets
DIN-rail expansion modules provide a structured platform for installing modular protective, switching and control devices within low-voltage distribution cabinets. The ABB MBG104 combines a compact 250 mm-wide 1PW format with 48 modular spaces distributed across four 35 × 15 mm DIN rails, providing substantial device capacity while maintaining the standardised internal layout of the CombiLine system.
With 125 mm row spacing and 12 modular spaces available on each DIN rail, the MBG104 provides a practical solution for building vertically organised device sections. Compatibility with ABB EDF and WR mounting frameworks makes it suitable for expandable professional distribution assemblies where consistent dimensions, modularity and efficient use of cabinet space are important.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- Sub-distribution boards and switchboards.
- DIN-rail mounted protective, switching and control devices.
- Modular electrical installation equipment according to DIN 43880.
- EDF and WR mounting-frame expansion applications.
- Commercial and industrial electrical distribution assemblies requiring up to 48 modular spaces.
