Why Choose the ABB MBG302 Modular Expansion 3PW?
The ABB MBG302 is an unassembled modular DIN rail expansion kit designed for ABB CombiLine sub-distribution assemblies. Supplied under ABB order code 2CPX041657R9999, it provides a structured mounting platform for DIN rail devices used within modular electrical distribution boards and cabinets.
The MBG302 features two 35 × 15 mm DIN rails with a row spacing of 125 mm and provides a total capacity of 72 modular spaces. Each DIN rail accommodates 36 modular spaces, while the three-field-width design incorporates an additional stabilisation rail to support the wider mounting arrangement.
With a height of 2 GU / 300 mm, a width of 3 PW / 750 mm and suitability for cabinets from 120 mm depth, the MBG302 provides a practical modular expansion solution for installation devices according to DIN 43880. Plastic covers with cut-outs provide a finished internal arrangement, while the appropriate EDF or WR mounting frame is ordered separately.

Structured DIN Rail Expansion for Distribution Assemblies
Modular expansion assemblies such as the ABB MBG302 provide a standardised platform for installing protective, switching and control devices on DIN rails within electrical distribution boards. The defined field dimensions and modular 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 mounting frames. With two DIN rails, 72 modular spaces and an additional stabilisation rail for its three-field-width configuration, the MBG302 provides a robust solution for larger groups of modular installation devices.
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.
