Why Choose the ABB MBG425 Modular Expansion 2PW?
The ABB MBG425 is a modular DIN rail device expansion kit designed for ABB CombiLine sub-distribution assemblies. Supplied under ABB order code 2CPX041674R9999, this kit provides a structured mounting solution for modular electrical devices within compatible distribution boards and cabinets.
The MBG425 is designed for installation devices according to DIN 43880 and uses 35 × 15 mm DIN rails. Its modular construction provides an organised platform for protective, switching and control devices while supporting consistent panel layouts within the ABB CombiLine interior fitting system.
With a height of 750 mm and a width of 500 mm, corresponding to a 5 GU × 2 PW configuration, the MBG425 provides capacity for 120 modular spaces. It uses 150 mm row spacing and is suitable for cabinets from 110 mm depth, while the required mounting frame is ordered separately.

Structured DIN Rail Expansion for Distribution Assemblies
Modular expansion assemblies such as the ABB MBG425 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 system enables configurable interior layouts using modular components and separate mounting structures. With its 5 GU height, 2 PW width and capacity for 120 modular spaces, the MBG425 is suited to larger groups of DIN rail devices where a structured multi-row installation is required.
Typical Applications
- ABB CombiLine 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.
- Multi-row modular electrical installations.
