Why Choose the ABB MG104 Modular Expansion?
The ABB MG104 is a factory-assembled CombiLine modular expansion module for DIN-rail devices, designed for installation within compatible ABB sub-distribution cabinets. Supplied under ABB order code 2CPX041215R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a 1 PW / 250 mm field width for professional distribution-board construction.
The MG104 provides 4 RE / 600 mm mounting height and a total of 48 modular space units. Four DIN rails provide 12 modular units per rail, with a 125 mm row spacing, creating an organised installation area for modular devices manufactured to DIN 43880.
The module uses 35 × 15 mm top-hat DIN rails with perforations for wire holders and features RAL 7035 plastic covers with cut-outs and 90-degree push-turn fasteners. It is suitable for cabinets from 120 mm deep, with the compatible EDF or WR mounting frame ordered separately.

Flexible Modular Expansion for Distribution Systems
Modular expansion modules provide structured mounting capacity for circuit protection, switching and other DIN-rail devices within electrical distribution systems. Standardised DIN rails and defined row spacing help installers create orderly equipment layouts while maintaining accessibility for wiring, inspection and future maintenance.
The ABB MG104 combines four equipment rows with 48 modular space units in a compact 1 PW format. Its CombiLine construction and compatibility with DIN 43880 devices make it well suited to professional distribution-board installations requiring organised modular equipment capacity.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine distribution systems.
- DIN-rail circuit protection device installations.
- Commercial building electrical distribution.
