Why Choose the ABB MBS228 Busbar Module Expansion 2PW?
The ABB MBS228 is a modular vertical busbar module expansion designed for ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine system and DESUJ Sub Distribution range, this unassembled kit provides a structured four-pole copper busbar system for reliable power distribution within compatible electrical cabinets.
The MBS228 incorporates four 30 × 5 mm copper busbars arranged vertically with a 40 mm busbar centre distance. The copper rails feature M6 threaded bores and M8 press-in nuts for connection, while ABB ZX518 busbar holders provide secure mechanical support throughout the assembly.
With a maximum rated current of 440 A, the MBS228 is configured for 2 panel widths (2PW) and measures 450 × 500 × 200 mm. It provides 72 space units and is suitable for expansion on compatible EDF or WR mounting frames in cabinets with a minimum depth of 200 mm.

Reliable Power Distribution for Modular Cabinets
Busbar modules such as the ABB MBS228 provide a structured low-resistance path for distributing electrical current through low-voltage distribution assemblies. Its four vertically aligned copper rails support an organised power distribution architecture while helping simplify cabinet construction, electrical connection and maintenance.
The ABB CombiLine modular system enables panel builders to combine compatible internal installation modules according to the required distribution layout. The MBS228 provides a two-panel-width vertical busbar section that can be integrated with compatible EDF or WR mounting structures for flexible cabinet construction.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- Commercial and industrial power distribution.
- Electrical panel and switchgear construction.
- Four-pole busbar distribution systems.
- Modular sub-distribution assemblies.
