Why Choose the ABB MN169 N+PE Busbar Expansion?
The ABB MN169 is a dedicated N+PE busbar expansion module designed for ABB CombiLine N sub-distribution systems. Supplied under ABB order code 2CPX041419R9999, this 1-panel-width module provides a structured horizontal neutral and protective-earth busbar arrangement for compatible low-voltage distribution cabinets.
The MN169 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 a module size of 150 × 250 mm, 12 PLE capacity and a maximum rated current of 320 A, the MN169 provides a compact solution for N and PE distribution. It is suitable for cabinets from 200 mm depth and can be installed using compatible ABB EDF or WR mounting frames, which must be ordered separately.

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 MN169 provides a compact horizontal 2-pole N+PE busbar arrangement within the CombiLine N system. Its 320 A 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.
