Why Choose the ABB MN269 N+PE Busbar Expansion?
The ABB MN269 is a dedicated N+PE busbar expansion module designed for ABB CombiLine N sub-distribution systems. Supplied under ABB order code 2CPX041420R9999, this 2-panel-width module provides a structured horizontal neutral and protective-earth busbar arrangement for compatible low-voltage distribution cabinets.
The MN269 is designed for a 2-pole horizontal busbar system and incorporates an ABB ZX518 busbar holder. It accommodates a maximum of two copper busbars with a 40 mm centre-to-centre distance, while the required copper busbars are ordered separately.
With dimensions of 150 × 500 × 200 mm, 24 PLE capacity and a maximum rated current of 320 A, the MN269 provides a practical solution for neutral and protective-earth distribution across two panel widths. Its closed plastic cover is finished in RAL 7035 and uses a 90-degree press-and-turn closure for straightforward access during installation and servicing.

Reliable Neutral and Protective-Earth Distribution
N and PE busbar systems provide dedicated connection and distribution points for neutral and protective-earth conductors within low-voltage electrical assemblies. A structured busbar module helps panel builders organise these connections while maintaining accessibility and a consistent internal distribution-board layout.
The ABB MN269 provides a horizontal 2-pole N+PE busbar arrangement within the CombiLine N system. Its 320 A maximum rated current, ZX518 busbar holder and provision for two copper rails make it suitable for professional sub-distribution assemblies requiring organised neutral and protective-earth distribution.
Typical Applications
- Commercial and industrial sub-distribution boards.
- Low-voltage electrical distribution cabinets.
- Neutral conductor distribution systems.
- Protective-earth conductor distribution systems.
- ABB CombiLine N modular distribution assemblies.
- Industrial switchboard and electrical panel-building projects.
