Why Choose the ABB MG203 Modular Expansion 2PW?
The ABB MG203 is a factory-assembled CombiLine modular expansion module for DIN rail-mounted devices designed for use within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041211R9999, it provides a structured internal mounting solution for modular protective, switching and control devices in sub-distribution assemblies.
The MG203 is configured for 2 panel widths (2 PW) with a field width of 500 mm and a module height of 450 mm. It provides 72 space units, giving panel builders substantial capacity for modular installation devices while maintaining an organised and standardised cabinet layout.
Designed for installation devices according to DIN 43880, the MG203 incorporates 35 × 15 mm DIN rails with a 125 mm row spacing. The module is supplied mounted and installed in the cabinet and is suitable for compatible enclosures from 120 mm depth. Plastic covers with device cut-outs, a 90-degree press-and-turn closure and a RAL 7035 finish complete the modular assembly.

Reliable Modular Expansion for Distribution Systems
Modular expansion modules provide a standardised internal platform for mounting protective, switching and control devices within low-voltage distribution boards. The ABB MG203 combines a generous 2 PW field width with three rows of DIN rail mounting space, helping panel builders organise modular equipment and associated wiring within a coordinated cabinet system.
As part of the ABB CombiLine system, the MG203 integrates with compatible EDF and WR mounting frames and supports installation devices manufactured to DIN 43880. Its 125 mm row spacing provides a compact arrangement for modular equipment, while the 72-space-unit capacity makes it suitable for distribution assemblies requiring a relatively high device density.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- Modular circuit protection installations.
- DIN rail-mounted switching and control devices.
- Commercial building electrical distribution systems.
