Why Choose the ABB MS324 Busbar Module Expansion?
The ABB MS324 is a factory-assembled CombiLine horizontal busbar module expansion for compatible ABB sub-distribution cabinets. Supplied under ABB order code 2CPX041274R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a 3 PW / 750 mm field width for structured power distribution.
The MS324 has a 2 RE / 300 mm height and provides 72 space units. It is designed for a horizontal busbar system with a 40 mm busbar centre distance, supports up to five copper busbars and is supplied with ZB5 busbar holders. The module is additionally braced in the middle to support its 3 PW width.
Rated for a maximum current of 360 A, the MS324 provides a robust solution for integrating horizontal busbar distribution into ABB CombiLine assemblies. The module features closed RAL 7035 plastic covers with 90-degree press-and-turn closures, is suitable from a cabinet depth of 225 mm, and requires the busbars and compatible EDF or WR mounting frame to be ordered separately.

Structured Horizontal Busbar Distribution
Busbar modules provide a structured method of distributing electrical power within professional distribution assemblies. The MS324's horizontal configuration accommodates up to five copper busbars at a 40 mm centre distance, providing a defined installation platform for power distribution while maintaining the modular architecture of the ABB CombiLine system.
With a 3 PW field width, 72 space units and maximum rated current of 360 A, the ABB MS324 is suited to distribution-board installations requiring a broad horizontal busbar section. Its ZB5 busbar holders, additional centre bracing and closed protective covers provide a system-compatible solution for professional sub-distribution assemblies.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine distribution systems.
- Horizontal busbar power-distribution sections.
- Commercial building electrical distribution.
- Industrial electrical distribution panels.
- Distribution-board extensions and power-distribution assemblies.
