Why Choose the ABB MBS224 Busbar Module Expansion 2PW?
The ABB MBS224 is a CombiLine horizontal busbar expansion module designed for structured power distribution within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041738R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides the supporting components required to integrate a horizontal copper busbar system into a professional distribution assembly.
Designed for a 2-panel-width (2PW) configuration, the MBS224 measures 300 × 500 × 200 mm and provides 48 space units. It supports a horizontal 5-pole busbar system with a 40 mm busbar centre distance, accommodates a maximum of 5 copper busbars and incorporates ZB5 busbar holders.
The MBS224 supports a maximum rated current of 360 A and is supplied as an unassembled, unequipped kit, allowing compatible copper busbars to be selected separately for the required installation. Closed RAL 7035 plastic covers with 90-degree press-and-turn fasteners provide a protected finished assembly, while a compatible EDF or WR mounting frame must be ordered separately.
Key Advantages
- Purpose-designed horizontal busbar module for ABB CombiLine distribution assemblies.
- Supports a maximum rated current of 360 A.
- Accommodates a maximum of 5 copper busbars in a 5-pole arrangement.
- 40 mm busbar centre spacing provides a compact, structured distribution system.
- 2-panel-width (2PW) format provides increased busbar length and distribution capacity within the cabinet layout.
- Supplied with ZB5 busbar holders and closed touch-protective covers.

Horizontal 5-Pole Busbar Distribution up to 360 A
Horizontal busbar systems provide an efficient method of distributing electrical power through low-voltage switchboard and sub-distribution assemblies. The ABB MBS224 provides the supporting structure for a 5-pole copper busbar system, positioning up to five rails at 40 mm centres within a 2PW CombiLine field.
The module is rated for applications up to 360 A and incorporates ZB5 busbar holders to maintain the required rail positioning. Because the copper busbars are ordered separately, the rail configuration can be selected to suit the required current capacity and cabinet arrangement while retaining the standardised CombiLine mounting architecture.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- Horizontal power distribution busbar systems.
- 5-pole low-voltage distribution arrangements.
- Commercial and industrial sub-distribution boards.
- Switchboard power distribution up to 360 A.
- Professional panel-building and system integration projects.
