Why Choose the ABB MM313 Mounting Plate Expansion?
The ABB MM313 is a factory-assembled CombiLine mounting plate expansion module designed for compatible ABB sub-distribution cabinets. Supplied under ABB order code 2CPX041250R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a 3 PW / 750 mm field width for mounting electrical equipment.
The MM313 has a 3 RE / 450 mm module height and provides 108 space units. Its mounting plate is manufactured from 2 mm sheet steel, providing a robust installation surface with a usable equipment width of 688 mm and usable height of 416 mm.
For flexible equipment positioning, the mounting plate is continuously adjustable in depth using mounting brackets, providing a usable depth range of 103–158 mm. The module features a closed RAL 7035 plastic cover with a 90-degree press-and-turn closure and is suitable for cabinets from 200 mm deep; the compatible EDF or WR mounting frame is ordered separately.
