Why Choose the ABB MBG204 Modular Expansion 2PW?
The ABB MBG204 is a CombiLine modular expansion module designed for DIN rail-mounted installation devices within compatible ABB low-voltage sub-distribution assemblies. Supplied as an unassembled kit under ABB order code 2CPX041667R9999, it provides a 2PW / two-field-width solution with four installation rows for structured mounting of modular electrical devices.
The MBG204 measures 600 mm high and 500 mm wide, corresponding to an installation height of 4 RE. It provides a total capacity of 96 PLE across four DIN rails, with 24 PLE per rail and a 125 mm row spacing for efficient use of cabinet space.
The module uses 35 × 15 mm DIN rails with perforations for wire holders and is designed for installation devices according to DIN 43880. Plastic covers with device cut-outs, a RAL 7035 finish and 90-degree press-and-turn fasteners provide a practical finished installation, while compatible EDF or WR mounting frames allow integration into ABB CombiLine cabinet interiors.

High-Capacity Four-Row DIN Rail Expansion Across Two Field Widths
The ABB MBG204 provides four dedicated rows for modular DIN rail-mounted devices across a 500 mm two-field-width format. Its four 35 × 15 mm DIN rails each provide 24 PLE, delivering a total installation capacity of 96 PLE within the 600 mm high module.
A compact 125 mm spacing between rows supports efficient device positioning, while perforations in the DIN rails provide provision for wire holders. Used with a compatible EDF or WR mounting frame, the MBG204 enables structured integration of modular protection, control and switching devices into ABB CombiLine low-voltage distribution cabinets.
Typical Applications
- ABB CombiLine modular sub-distribution assemblies.
- DIN rail-mounted modular electrical devices.
- Low-voltage distribution boards and cabinets.
- Commercial and industrial electrical installations.
- Multi-row switchgear and protection-device sections.
- Panel building, cabinet expansion and refurbishment projects.
