Why Choose the ABB MS124 Busbar Module Expansion 1PW?
The ABB MS124, order code 2CPX041272R9999, is a horizontal busbar module designed for ABB CombiLine sub-distribution systems. Supplied as a mounted interior expansion module, it provides a structured solution for integrating a horizontal busbar system into compatible low-voltage distribution cabinets.
Designed for professional electrical distribution applications, the MS124 supports a maximum rated current of 360 A and accommodates up to five copper busbars. The module uses a 40 mm busbar centre distance and includes a ZB5 busbar holder, while the required copper busbars are ordered separately. Its closed plastic cover provides touch protection and uses a practical 90-degree push-turn fastener.
The MS124 occupies 1 panel width (PW/FB) and 2 grid units (GU/RE), with nominal dimensions of 300 mm high × 250 mm wide and 24 space units. It is suitable for installations from a cabinet depth of 200 mm and is designed for use with compatible EDF or WR mounting frames.

Reliable Power Distribution with the ABB CombiLine System
Busbar modules provide an organised method of distributing electrical power within low-voltage switchgear and distribution assemblies. The ABB MS124 is designed around a horizontal busbar arrangement with a 40 mm centre distance, providing capacity for up to five copper busbars and a maximum rated current of 360 A.
As part of the ABB CombiLine interior expansion system, the MS124 enables modular construction of professional sub-distribution assemblies. Its compact 1-panel-width format, ZB5 busbar holder and closed protective cover simplify integration into compatible cabinet systems while maintaining a structured and protected distribution arrangement. Copper busbars and the EDF or WR mounting frame are ordered separately.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial sub-distribution systems.
- ABB CombiLine panel assemblies.
- Horizontal power distribution within electrical cabinets.
- Five-pole busbar distribution systems.
- Electrical switchgear and control cabinets requiring busbar currents up to 360 A.
