Why Choose the ABB MG304 Modular Expansion 3PW?
The ABB MG304, order code 2CPX041219R9999, is a mounted CombiLine DIN rail modular expansion assembly designed for professional electrical sub-distribution systems. Its 3PW / 3-field configuration provides a substantial 750 mm-wide installation area for modular DIN rail devices within compatible ABB distribution enclosures.
The MG304 measures 750 mm wide × 600 mm high × 120 mm deep and provides 144 modular spaces across four DIN rails. Each rail accommodates 36 modular spacings, while the 125 mm row spacing supports an organised layout for compatible installation devices.
The assembly uses 35 × 15 mm perforated DIN rails, with an additional stabilisation profile for the three-field-wide configuration. Plastic covers with cut-outs, a 90-degree press-and-turn closure and an RAL 7035 finish complete the assembly, which can be used from a cabinet depth of 120 mm with the appropriate separately ordered EDF or WR mounting frame.

High-Capacity DIN Rail Expansion for Distribution Systems
DIN rail mounting modules provide structured installation space for protective, switching, control and other modular devices within electrical distribution assemblies. The ABB MG304 combines four 35 × 15 mm DIN rails with a total capacity of 144 modular spaces, providing substantial equipment capacity within one three-field-wide CombiLine section.
With its 600 mm height, 750 mm width and 125 mm row spacing, the MG304 is suited to larger distribution assemblies requiring four rows of modular devices. The module is supplied mounted and can be integrated with compatible EDF or WR mounting systems, with the appropriate mounting frame ordered separately.
Typical Applications
- Electrical sub-distribution systems.
- High-capacity DIN rail device installations.
- ABB CombiLine interior expansion systems.
- EDF and WR mounting-frame assemblies.
- Commercial building distribution boards.
- Industrial electrical panels.
- Modular protection, switching and control equipment installations.
- Distribution-board expansion and refurbishment projects.
