Why Choose the ABB MG435 Modular Expansion 3PW?
The ABB MG435 is a factory-assembled CombiLine modular expansion module for DIN rail-mounted devices designed for installation within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041226R9999, it provides a high-capacity internal mounting solution for modular protective, switching and control devices in sub-distribution assemblies.
The MG435 is configured for 3 panel widths (3 PW) with a field width of 750 mm and a module height of 750 mm. It provides 180 space units across five DIN rail rows, with 36 modular spaces per rail, making it particularly suitable for larger distribution boards requiring substantial modular device capacity.
Designed for installation devices according to DIN 43880, the MG435 incorporates five 35 × 15 mm DIN rails with a generous 150 mm row spacing. The 3 PW rails include additional stabilisation profiles, while plastic covers with device cut-outs, a 90-degree press-and-turn closure and a RAL 7035 finish provide a coordinated installation. The module can be used in compatible cabinets from 120 mm depth.

Reliable Modular Expansion for Distribution Systems
Modular expansion modules provide a standardised internal platform for mounting protective, switching and control equipment within low-voltage distribution boards. The ABB MG435 combines five DIN rail rows with 180 available space units, enabling panel builders to accommodate a substantial quantity of modular equipment while maintaining an organised and accessible internal layout.
The 150 mm row spacing provides additional room between DIN rails for equipment installation, conductor routing and wiring work. As part of the ABB CombiLine system, the MG435 integrates with compatible EDF or WR mounting frames and provides a coordinated solution for larger commercial and industrial distribution assemblies.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- High-capacity modular circuit protection installations.
- DIN rail-mounted switching and control equipment.
- Commercial building electrical distribution systems.
- Industrial distribution and control panels.
