Why Choose the ABB MBG304 Modular Expansion 3PW?
The ABB MBG304 is a modular expansion kit designed for ABB electrical distribution assemblies, providing a practical 3PW expansion section for structured low-voltage distribution and switchboard installations. Supplied under ABB order code 2CPX041669R9999, the MBG304 forms part of ABB's modular distribution system portfolio for professional panel building and electrical distribution applications.
The MBG304 is supplied as a kit for modular assembly, allowing panel builders and electrical engineers to extend compatible ABB distribution systems while maintaining a consistent mechanical arrangement. Its modular format supports organised installation of distribution equipment and provides additional usable panel space when expanding an existing assembly.
This 3PW version has an overall nominal height of 600 mm, width of 850 mm and depth of 120 mm. The MBG304 is the kit-supplied version associated with the corresponding ABB MG304 assembled expansion, making it suitable where on-site or workshop assembly is preferred.

Reliable Expansion for Modular Distribution Systems
Modular expansion sections such as the ABB MBG304 enable electrical distribution assemblies to be extended in a structured and repeatable way. Additional panel space can be incorporated into the installation while retaining an organised arrangement for electrical devices, internal wiring and associated distribution components.
By supplying the MBG304 in kit form, ABB provides panel builders with flexibility during switchboard construction and assembly. The component is particularly suited to professional distribution-board and control-panel projects where compatible ABB modular sections are combined to create a complete installation.
Typical Applications
- Low-voltage electrical distribution assemblies.
- Commercial and industrial distribution boards.
- Modular switchboard extensions.
- Electrical panel building and system integration.
- Power distribution and control installations.
- ABB modular distribution system expansion projects.
