Why Choose the ABB MBG423 Modular Expansion 2PW?
The ABB MBG423 is a modular DIN rail device expansion module designed for structured internal fitting of ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine system and DESUJ Sub Distribution range, it provides an organised mounting platform for modular DIN rail devices within compatible electrical cabinets.
The MBG423 is configured with three 35 × 15 mm DIN rails, each providing 24 modular spaces. This gives the module a total capacity of 72 space units, with a 150 mm row spacing suitable for modular devices manufactured to DIN 43880.
Configured for 2 panel widths (2PW), the MBG423 measures 450 × 500 × 120 mm. It features plastic covers with cut-outs, a 90-degree press-and-turn fixing system and a RAL 7035 finish, and it can be used in cabinets from 120 mm depth with a compatible EDF or WR mounting frame.

Structured DIN Rail Installation for Distribution Systems
Modular expansion units such as the ABB MBG423 provide a dedicated internal mounting area for protective, switching and control devices installed on standard DIN rails. The three-row arrangement helps panel builders organise equipment and wiring while maintaining accessibility for installation, inspection and servicing.
The ABB CombiLine system uses modular internal fitting components to support flexible distribution cabinet layouts. With two panel widths and 72 modular spaces, the MBG423 provides substantial DIN rail capacity while retaining a structured and space-efficient cabinet arrangement.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- DIN rail protective and switching devices.
- Commercial and industrial electrical panels.
- Control and power distribution cabinets.
- Modular sub-distribution assemblies.
