Why Choose the ABB MBS227 Busbar Module Expansion 2PW?
The ABB MBS227 is an unassembled horizontal busbar system expansion module designed for ABB CombiLine N sub-distribution assemblies. Supplied under ABB order code 2CPX041741R9999, it provides a structured mounting arrangement for a three-pole copper busbar system within compatible electrical distribution boards and cabinets.
The MBS227 uses ZX151 busbar holders and provides a 60 mm busbar centre distance for a maximum of three copper busbars. The module supports a maximum rated current of 630 A, making it suitable for substantial power-distribution duties within compatible ABB assemblies. The required copper busbars are ordered separately.
With a height of 2 GU / 300 mm, a width of 2 PW / 500 mm and a depth of 215 mm, the MBS227 provides 48 space units. Closed RAL 7035 plastic covers with 90-degree press-and-turn closures provide a neat finished arrangement, while the appropriate EDF or WR mounting frame must be ordered separately.

Reliable Busbar Distribution for Electrical Assemblies
Busbar modules such as the ABB MBS227 provide a structured method of distributing electrical power through low-voltage distribution assemblies. The horizontal three-pole arrangement allows copper busbars to carry substantial currents efficiently while providing a standardised platform for integration with compatible distribution equipment.
The ABB CombiLine N system supports configurable distribution-board interiors and allows different module widths to be combined with continuous busbars where required. With its 630 A maximum rated current, 60 mm busbar spacing and ZX151 holders, the MBS227 provides a robust foundation for three-pole power distribution within compatible cabinets.
Typical Applications
- ABB CombiLine N modular distribution assemblies.
- Three-pole horizontal busbar systems.
- Commercial and industrial sub-distribution boards.
- Low-voltage electrical distribution cabinets.
- Panel-building and switchboard applications.
- High-current power distribution within modular enclosures.
