Why Choose the ABB MBS127 Busbar Module Expansion?
The ABB MBS127 is a CombiLine busbar module expansion kit designed for horizontal busbar systems within ABB low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041740R9999, it belongs to ABB’s DESUJ Sub Distribution product group and provides a compact platform for professional power distribution within electrical cabinets.
The MBS127 is supplied as an unassembled internal installation module for a 3-pole horizontal busbar system. It features a 60 mm busbar centre distance, supports up to 3 copper busbars and incorporates an ABB ZX151 busbar holder. The module is rated for a maximum current of 630 A, while the required copper busbars are ordered separately.
With a module height of 300 mm, a compact 1PW field width of 250 mm and 24 space units, the MBS127 provides an efficient busbar installation solution where cabinet space is limited. It is suitable for cabinets from 215 mm depth and can be combined with compatible ABB EDF or WR mounting frames, which are ordered separately.

Reliable Horizontal Busbar Distribution for Electrical Panels
Horizontal busbar modules provide a structured platform for distributing substantial electrical currents through low-voltage switchboards and distribution assemblies. By supporting continuous copper busbars across compatible installation fields, the system enables efficient power distribution while maintaining an organised and coordinated internal panel layout.
The ABB MBS127 combines a 60 mm busbar centre distance, support for up to 3 copper busbars and a maximum rated current of 630 A in a compact 1PW format. Its ZX151 busbar holder and compatibility with multiple copper rail sizes make it a practical solution for professional CombiLine installations requiring high-current horizontal busbar distribution in a relatively small field width.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine electrical distribution assemblies.
- Three-pole horizontal copper busbar systems.
- Commercial and industrial distribution cabinets.
- Electrical panel building and cabinet expansion.
- Power distribution systems requiring busbar capacity up to 630 A.
