Why Choose the ABB MBS324 Busbar Module Expansion?
The ABB MBS324 is a CombiLine busbar module expansion kit designed for horizontal busbar systems within ABB low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041739R9999, it belongs to ABB’s DESUJ Sub Distribution product group and provides a purpose-designed platform for professional high-current distribution within electrical cabinets.
The MBS324 is supplied as an unassembled internal installation module for a horizontal busbar system with a 40 mm busbar centre distance. It supports up to 5 copper busbars, incorporates ABB ZB5 busbar holders and ZX172 end covers, and is designed for a maximum rated current of 360 A. The busbars themselves are ordered separately.
With a module height of 300 mm, a 3PW field width of 750 mm and 72 space units, the MBS324 provides a wide installation field for horizontal power distribution. The 3PW design incorporates additional central bracing for mechanical support and is suitable for cabinets from 225 mm depth, with the required EDF or WR mounting frame 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 the installation field, the system enables efficient power distribution while maintaining an organised and coordinated internal panel layout.
The ABB MBS324 combines a 40 mm busbar centre distance, support for up to 5 copper busbars and a maximum rated current of 360 A in a spacious 3PW format. Its ZB5 busbar holders, ZX172 end covers and additional central bracing make it a practical solution for professional CombiLine sub-distribution installations requiring robust horizontal busbar support.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine electrical distribution assemblies.
- Horizontal copper busbar systems.
- Commercial and industrial distribution cabinets.
- Electrical panel building and cabinet expansion.
- Power distribution systems rated up to 360 A.
