Why Choose the ABB MBG305 Modular Expansion 3PW?
The ABB MBG305 is an unassembled modular DIN rail expansion kit designed for ABB CombiLine-M sub-distribution assemblies. Supplied under ABB order code 2CPX041675R9999, it provides a structured mounting platform for modular electrical devices within compatible distribution boards and cabinets.
The MBG305 is designed for mounting equipment on 35 × 15 mm DIN rails and provides a total capacity of 180 modular spaces. Its multi-row arrangement uses 125 mm spacing between DIN rails, providing an organised installation platform for protective, switching and control devices.
With a height of 5 GU / 750 mm and a width of 3 PW / 750 mm, the MBG305 is a high-capacity modular expansion for larger distribution assemblies. It is suitable for cabinets with a minimum depth of 120 mm, making it well suited to structured commercial and industrial panel-building applications.

Structured DIN Rail Expansion for Distribution Assemblies
Modular expansion assemblies such as the ABB MBG305 provide a standardised platform for installing protective, switching and control devices on DIN rails within electrical distribution boards. Defined grid dimensions and DIN rail spacing help panel builders organise equipment consistently while supporting efficient wiring, inspection and maintenance.
The ABB CombiLine-M system provides modular interior components for configurable electrical distribution assemblies. With its 3 PW width, 5 GU height and capacity for 180 modular spaces, the MBG305 is particularly suited to applications requiring a large quantity of DIN rail mounted equipment within a structured panel layout.
Typical Applications
- ABB CombiLine-M modular distribution assemblies.
- Commercial and industrial sub-distribution boards.
- DIN rail protective and switching device installation.
- Electrical distribution and control cabinets.
- Panel-building and switchboard applications.
- High-capacity multi-row modular electrical installations.
