Why Choose the ABB MBS327 Busbar Module Expansion 3PW?
The ABB MBS327 is an unassembled horizontal busbar system expansion module designed for ABB CombiLine N modular distribution assemblies. Supplied under ABB order code 2CPX041742R9999, it provides a structured mounting arrangement for a three-pole copper busbar system within compatible electrical distribution boards and cabinets.
The MBS327 uses ZX151 busbar holders with a 60 mm busbar centre distance and accommodates a maximum of three copper busbars. It supports busbars up to 30 × 10 mm and a maximum rated current of 630 A, while its three-field-width construction is additionally braced in the middle for mechanical support.
With a height of 300 mm, width of 750 mm and depth of 225 mm, the MBS327 corresponds to a 2 GU × 3 PW configuration and provides 72 space units. Closed RAL 7035 plastic covers with 90-degree press-and-turn closures complete the module, while the required copper busbars and mounting frame are ordered separately.

Reliable Busbar Distribution for Electrical Assemblies
Busbar modules such as the ABB MBS327 provide a structured method of distributing electrical power through low-voltage distribution assemblies. The horizontal three-pole arrangement enables 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, ZX151 holders and additional central bracing, the MBS327 provides a robust solution for three-field-width power distribution.
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.
