Why Choose the ABB MG305 Modular Expansion 3PW?
The ABB MG305 is a factory-assembled CombiLine modular expansion module for DIN rail-mounted devices designed for use within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041225R9999, it provides a high-capacity internal mounting solution for modular protective, switching and control devices in sub-distribution assemblies.
The MG305 is configured for 3 panel widths (3 PW) with a field width of 750 mm and a module height of 750 mm. It provides 180 space units across five DIN rail rows, with 36 space units available per rail, making it suitable for distribution boards requiring substantial modular device capacity.
Designed for installation devices according to DIN 43880, the MG305 incorporates five 35 × 15 mm DIN rails with 125 mm row spacing. The 3 PW rail arrangement includes additional stabilisation rails, while plastic covers with device cut-outs, a 90-degree press-and-turn closure and a RAL 7035 finish provide a coordinated installation. The module is suitable for compatible cabinets from 120 mm depth.

Reliable Modular Expansion for Distribution Systems
Modular expansion modules provide a standardised internal platform for protective, switching and control devices within low-voltage distribution boards. The ABB MG305 combines five DIN rail rows with a total capacity of 180 space units, allowing panel builders to accommodate a substantial number of modular devices while maintaining an organised and accessible equipment layout.
As part of the ABB CombiLine system, the MG305 integrates with compatible EDF or WR mounting frames and supports modular devices manufactured according to DIN 43880. Its 125 mm row spacing, reinforced 3 PW rail arrangement and factory-assembled format make it particularly suitable for larger commercial and industrial distribution assemblies requiring high modular device density.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- High-capacity modular circuit protection installations.
- DIN rail-mounted switching and control equipment.
- Commercial building electrical distribution systems.
- Industrial distribution and control panels.
- Panel-building applications requiring extensive modular device capacity.
