Why Choose the ABB MBG434 Modular Expansion?
The ABB MBG434 is a CombiLine modular expansion kit designed for mounting DIN rail devices within ABB low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041670R9999, it belongs to ABB’s DESUJ Sub Distribution product group and provides a structured internal installation solution for professional distribution boards and electrical cabinets.
The MBG434 is supplied as an unassembled internal installation module for DIN rail-mounted equipment. It provides 144 modular spaces across four rows, with a 150 mm row spacing and 35 × 15 mm perforated DIN rails. For this 3PW configuration, the DIN rails incorporate additional stabilisation to support the wider installation field.
With a module height of 600 mm, a 3PW field width of 750 mm and suitability for cabinets from 120 mm depth, the MBG434 provides substantial capacity for modular protective, switching and control equipment. Compatible EDF or WR mounting frames are required and ordered separately.
