Why Choose the ABB MG301 Modular Expansion 3PW?
The ABB MG301, order code 2CPX041202R9999, is a mounted modular expansion assembly for DIN rail devices designed for ABB CombiLine N electrical sub-distribution systems. Its 3PW / 3-field width provides a wide modular section for accommodating rail-mounted installation devices within professional distribution boards and enclosure systems.
The MG301 is designed for DIN rail-mounted devices according to DIN 43880 and uses 35 × 15 mm DIN rails. With a row spacing of 125 mm, a height of 1 RE / 150 mm and a width of 3 fields / 750 mm, it provides capacity for up to 36 modular units in compatible ABB mounting-frame systems.
Designed for use from a cabinet depth of 120 mm, the MG301 is compatible with EDF and WR mounting systems. The assembly is supplied mounted rather than as an unassembled kit, making it a practical solution for panel builders requiring a ready-configured modular expansion section within ABB CombiLine N installations.

Flexible DIN Rail Expansion for Distribution Systems
Modular expansion assemblies provide dedicated DIN rail space for protective, switching and control devices within electrical distribution systems. The ABB MG301 uses standard 35 × 15 mm DIN rails and provides capacity for up to 36 modular units, enabling panel builders to organise compatible DIN rail equipment efficiently within a defined CombiLine N section.
With its 3-field width and 125 mm row spacing, the MG301 is suited to wider modular distribution arrangements where a single 750 mm section is required. Compatibility with EDF and WR mounting systems allows straightforward integration into appropriate ABB distribution-board configurations, while the mounting frame itself is specified separately where required.
Typical Applications
- Electrical sub-distribution systems.
- DIN rail device expansion within distribution boards.
- ABB CombiLine N interior systems.
- EDF and WR mounting-frame assemblies.
- Commercial building distribution boards.
- Industrial electrical panels.
- Modular protection, switching and control equipment installations.
