Why Choose the ABB MG204 Modular Expansion 2PW?
The ABB MG204 is a modular expansion unit for DIN rail-mounted devices designed for structured interior installation within ABB CombiLine electrical distribution systems. Supplied under ABB order code 2CPX041217R9999, this two-field-width module is supplied assembled for cabinet installation and provides dedicated mounting space for modular devices in low-voltage distribution and switchgear assemblies.
The MG204 provides a 4 RE / 600 mm module height and a 2 FB / 500 mm field width, giving a total capacity of 96 space units. Four DIN-rail rows provide 24 modular spaces per rail, allowing protective, switching and control devices to be arranged systematically across the cabinet interior.
Designed for installation devices according to DIN 43880, the MG204 uses 35 × 15 mm DIN rails with perforations for wire holders and has a 125 mm row spacing. Plastic covers with cut-outs, 90-degree push-turn fasteners and a RAL 7035 finish complete the assembly, while compatibility from a cabinet depth of 120 mm supports space-efficient distribution-board construction.

Structured Modular Device Installation for Distribution Cabinets
Modular expansion units such as the ABB MG204 provide dedicated DIN-rail mounting space for protective, switching and control devices within electrical distribution assemblies. Its four-row arrangement, 96-space-unit capacity and 125 mm row spacing help create an organised cabinet layout while maintaining practical access for installation, wiring and maintenance.
As part of the ABB CombiLine interior expansion system, the MG204 is designed for modular installation devices according to DIN 43880. Its 35 × 15 mm DIN rails and two-field-width format make it suitable for building structured low-voltage distribution assemblies, with the appropriate EDF or WR mounting frame ordered separately.
Typical Applications
- Low-voltage electrical distribution cabinets.
- ABB CombiLine interior expansion systems.
- Sub-distribution boards and switchgear assemblies.
- DIN rail-mounted protective and switching devices.
- Commercial and industrial electrical installations.
- Control and distribution cabinet interior expansion.
