Why Choose the ABB MBG433 Modular Expansion 3PW?
The ABB MBG433, order code 2CPX041664R9999, is an unassembled CombiLine interior expansion module designed for DIN-rail mounted devices in compatible ABB low-voltage distribution cabinets. Part of the DESUJ Sub Distribution product group, it provides a system-matched solution for creating high-capacity modular device rows within professional switchboards and sub-distribution assemblies.
Designed for a 3PW field width of 750 mm, the MBG433 provides 3 grid units (GU), equivalent to 450 mm height, and a total of 108 modular spaces. Three 35 × 15 mm DIN rails provide 36 modular spaces per rail, giving panel builders substantial installation capacity within a standardised CombiLine format.
The MBG433 uses 150 mm row spacing and is designed for modular installation devices according to DIN 43880. Its three-field-wide DIN rails incorporate additional stabilisation profiles for mechanical support, while the RAL 7035 plastic covers feature device cut-outs and 90-degree press-and-turn closures. The module can be used from a cabinet depth of 120 mm with a compatible EDF or WR mounting framework.

High-Capacity DIN-Rail Expansion for ABB CombiLine Cabinets
DIN-rail expansion modules provide a structured platform for installing modular protective, switching and control devices within low-voltage distribution cabinets. The ABB MBG433 combines a 750 mm-wide 3PW format with 108 modular spaces distributed across three 35 × 15 mm DIN rails, providing substantial installation capacity while maintaining the standardised internal layout of the CombiLine system.
With 150 mm row spacing and additional stabilisation profiles supporting its wide DIN rails, the MBG433 is designed for mechanically stable professional panel construction. Compatibility with ABB EDF and WR mounting frameworks makes it a practical system component for organised, expandable and high-density modular distribution assemblies.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- High-capacity sub-distribution boards and switchboards.
- DIN-rail mounted protective, switching and control devices.
- Modular electrical installation equipment according to DIN 43880.
- EDF and WR mounting-frame expansion applications.
- Commercial and industrial electrical distribution assemblies requiring up to 108 modular spaces.
