Why Choose the ABB MG105 Modular Expansion 1PW?
The ABB MG105, order code 2CPX041221R9999, is a mounted CombiLine modular interior expansion module for DIN rail-mounted devices designed for ABB electrical sub-distribution systems. Part of the ABB CombiLine series and the DESUJ Sub Distribution product group, it provides an organised and space-efficient solution for installing modular protective, switching and control devices inside electrical distribution cabinets.
Designed for devices manufactured in accordance with DIN 43880, the MG105 provides 60 module positions across five rows. Its 5 RE configuration has an overall height of 750 mm and a single-field width of 250 mm, making it suitable for installations requiring substantial DIN rail capacity within a narrow cabinet field.
The MG105 is assembled with 35 × 15 mm DIN rails featuring perforations for wire holders and incorporates plastic covers with cut-outs and 90-degree push-turn closures. Finished in RAL 7035 light grey, the module is suitable for cabinets from 120 mm depth and is designed for installation using an ABB EDF or WR mounting frame, which is ordered separately.

Flexible Interior Expansion for Distribution Systems
Modular interior expansion systems such as the ABB CombiLine range provide structured mounting space for protective, switching and control equipment within electrical distribution cabinets. Standardised DIN rail mounting and defined equipment spacing help simplify panel layout, installation and wiring while supporting future modifications to the distribution system.
The MG105 is particularly suited to applications requiring a tall, narrow equipment field, combining five rows and 60 module positions within a 250 mm field width. Its mounted construction, DIN rail arrangement and compatibility with ABB EDF or WR mounting frames make it a practical solution for professional switchboard and sub-distribution installations.
Typical Applications
- Commercial and industrial sub-distribution boards.
- Electrical distribution cabinets and switchboards.
- DIN rail protective device installations.
- Building-services electrical distribution systems.
- Modular switching and control equipment assemblies.
- ABB CombiLine cabinet expansion and interior fit-out.
