Why Choose the ABB MG432 CombiLine Modular Expansion Module?
The ABB MG432 is a CombiLine modular expansion module designed for DIN rail-mounted electrical devices within compatible ABB sub distribution assemblies. Identified by ABB order code 2CPX041208R9999, it provides a factory-assembled internal mounting solution with a 3-panel-width format for professional low-voltage distribution systems.
The MG432 has a nominal module size of 300 mm high × 750 mm wide, corresponding to 2 grid units and 3 panel widths. It provides 72 modular spaces arranged across two DIN rails, with 36 modular spaces per rail and a row spacing of 150 mm.
Designed for equipment conforming to DIN 43880, the module incorporates 35 × 15 mm DIN rails with perforations for wire holders and an additional stabilisation rail for the wide three-panel configuration. Plastic covers with cut-outs and 90-degree press-turn fasteners complete the assembly, while a compatible ABB EDF or WR mounting frame is ordered separately.

Flexible DIN Rail Expansion with ABB CombiLine
The ABB CombiLine system enables modular internal layouts to be created for professional low-voltage distribution assemblies. The MG432 provides 72 modular spaces across two DIN rails, giving installers substantial capacity for compatible circuit protection, switching, control and other DIN rail-mounted devices within a standardised three-panel-width module.
Its 150 mm row spacing and 35 × 15 mm DIN rails provide an organised installation platform for devices manufactured to DIN 43880. The additional stabilisation rail reinforces the wide DIN rail arrangement, while the standardised CombiLine format enables the MG432 to be combined with other compatible modules within an appropriate ABB mounting frame and enclosure.
Typical Applications
- Commercial low-voltage sub distribution assemblies.
- Industrial electrical distribution systems.
- DIN rail-mounted circuit protection equipment.
- Building-services electrical installations.
- Control and switching device installations.
- ABB CombiLine modular distribution assemblies requiring a high-capacity 3-panel-width DIN rail module.
