Why Choose the ABB MBG422 Modular Expansion 2PW?
The ABB MBG422 is a modular DIN rail mounting device expansion kit designed for ABB CombiLine sub-distribution assemblies. Supplied under ABB order code 2CPX041656R9999, this unassembled interior fitting module provides an organised mounting platform for modular DIN rail devices in electrical distribution boards and cabinets.
The MBG422 features two DIN rails with a row spacing of 150 mm and provides a total capacity of 48 modular spaces. Its DIN rails are 35 × 15 mm and incorporate perforations for wire holders, supporting neat device mounting and cable organisation within compatible ABB distribution assemblies.
With a grid height of 2 GU / 300 mm, a panel width of 2 PW / 500 mm and a depth of 120 mm, the MBG422 provides a practical modular expansion solution for DIN rail devices according to DIN 43880. The module includes plastic covers with cut-outs and is designed for use with compatible EDF or WR mounting frames, which are ordered separately.

Structured DIN Rail Expansion for Distribution Assemblies
Modular expansion assemblies such as the ABB MBG422 provide a standardised platform for installing protective, switching and control devices on DIN rails inside electrical distribution boards. The defined grid dimensions and modular spacing help panel builders organise devices consistently while maintaining convenient access for wiring, inspection and maintenance.
The ABB CombiLine system supports configurable interior layouts using modular components and mounting frames. With two DIN rails and 48 modular spaces, the MBG422 provides substantial device capacity within a compact 2 PW field and integrates with compatible EDF or WR mounting structures.
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.
- Modular electrical installation systems.
