Why Choose the ABB MN369 N+PE Busbar Expansion Module?
The ABB MN369, order code 2CPX041421R9999, is a mounted N+PE busbar expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a dedicated horizontal neutral and protective-earth busbar arrangement for professional commercial and industrial sub-distribution cabinets.
The MN369 is designed for a 2-pole horizontal N+PE busbar system and uses ABB ZX518 busbar holders with 40 mm busbar centre spacing. It accommodates a maximum of two copper busbars, which are ordered separately, and supports a maximum rated current of 320 A. The three-panel-width design also incorporates additional centre support for the extended busbar span.
With a module height of 1 GU / 150 mm, a panel width of 3 PW / 750 mm and 36 space units, the MN369 provides a full-width N+PE distribution solution within the CombiLine system. It is suitable for cabinets from 200 mm depth and can be installed on compatible ABB EDF or WR mounting frames, which must be ordered separately.

Reliable Neutral and Protective-Earth Distribution
N+PE busbar systems provide centralised connection points for neutral and protective-earth conductors within electrical distribution assemblies. The ABB MN369 provides a 2-pole horizontal busbar arrangement across a 750 mm panel width, helping panel builders create organised, accessible and reliable N and PE conductor distribution within CombiLine cabinets.
The MN369 uses ABB ZX518 busbar holders with 40 mm centre spacing and accommodates two copper busbars selected separately according to the required current capacity. For the full three-panel-width configuration, the busbar arrangement is additionally supported in the centre, while a maximum rated current of 320 A supports demanding commercial and industrial sub-distribution applications.
Typical Applications
- Commercial and industrial sub-distribution boards.
- ABB CombiLine electrical cabinet assemblies.
- Neutral conductor distribution.
- Protective-earth conductor distribution.
- Industrial switchgear and distribution cabinets.
- Panel building and modular electrical distribution installations.
