Why Choose the ABB MBG203 Modular Expansion 2PW?
The ABB MBG203 is a CombiLine modular distribution expansion module designed for DIN-rail-mounted electrical devices within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041661R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a structured mounting solution for modular protection, switching and control equipment.
The MBG203 is supplied as an unassembled kit and provides 3 DIN-rail rows, each accommodating 24 modular spaces, giving a total capacity of 72 modular spaces. The rows are arranged at 125 mm centres and use 35 × 15 mm DIN rails with perforations for wire holders, making the module suitable for modular devices conforming to DIN 43880.
Designed for a 2-panel-width (2PW) configuration, the MBG203 measures 450 × 500 × 120 mm. Plastic covers with equipment cut-outs, a RAL 7035 finish and 90-degree press-and-turn fasteners provide a practical finished installation, while a compatible EDF or WR mounting frame is ordered separately.

Flexible Modular Distribution for DIN-Rail Devices
DIN-rail modular distribution systems provide an organised method of installing circuit protection, switching, control and other modular electrical devices within low-voltage distribution cabinets. Standardised DIN rails allow compatible equipment to be positioned securely while maintaining accessible wiring routes and a structured panel layout.
The ABB MBG203 provides three equipment rows with a total of 72 modular spaces and 125 mm row spacing, making it particularly suitable for distribution assemblies requiring greater device capacity within a 2PW section. Its CombiLine design allows it to be combined with compatible ABB mounting frames and cabinet components to create a structured professional distribution system.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- DIN-rail circuit protection and switching devices.
- Electrical sub-distribution assemblies.
- Commercial and industrial switchboards.
- Modular control and distribution equipment.
- Professional panel-building and system integration projects.
