Why Choose the ABB MS228 440A Busbar Module?
The ABB MS228, order code 2CPX041124R9999, is a 440 A vertical busbar interior fitting module from the ABB CombiLine range. Supplied as a mounted module for installation in a compatible cabinet, it provides a coordinated four-pole copper busbar system for professional low-voltage sub-distribution assemblies.
The MS228 occupies 3 grid units (450 mm) in height and 2 panel widths (500 mm), providing 72 space units. Its busbar system comprises four vertical 30 × 5 mm copper busbars with a 40 mm centre distance, supported by ABB ZX518 busbar holders and rated for a maximum current of 440 A.
Designed for installation from a cabinet depth of 200 mm, the MS228 is compatible with EDF and WR mounting frames, which are ordered separately. Closed RAL 7035 plastic covers with 90° press-and-turn closures provide a coordinated protective finish, while the module's two-panel-width format makes it suitable for larger busbar distribution arrangements within ABB CombiLine assemblies.

440A Vertical Busbar Distribution with ABB CombiLine
A vertical busbar module provides a structured method of distributing electrical power through a compatible low-voltage distribution assembly. The ABB MS228 uses four 30 × 5 mm copper busbars arranged vertically with a 40 mm centre distance, providing a maximum rated current of 440 A and a short-time withstand current of 20 kA.
Its 450 × 500 mm modular format provides 72 space units across two panel widths, offering greater installation capacity than the single-width MS128. Compatibility with both EDF and WR mounting frames allows the MS228 to integrate into coordinated ABB CombiLine sub-distribution assemblies from a cabinet depth of 200 mm.
Typical Applications
- Low-voltage electrical sub-distribution systems.
- ABB CombiLine distribution assemblies.
- Vertical 440 A busbar distribution systems.
- Commercial building electrical distribution.
- Industrial low-voltage distribution assemblies.
- Two-panel-width busbar installations.
- EDF mounting-frame installations.
- WR mounting-frame installations.
- Professional switchboard and panel-building applications.
