Why Choose the ABB MBN269 N+PE Busbar Expansion 2PW?
The ABB MBN269, order code 2CPX041425R9999, is an unpopulated N/PE horizontal busbar expansion module designed for ABB CombiLine low-voltage sub-distribution systems. Supplied as an unassembled kit, it provides a dedicated 2-pole platform for neutral and protective-earth busbars within professional electrical distribution assemblies.
The MBN269 is designed for a 2-pole horizontal busbar system with a maximum rated current of 320 A. It uses an ABB ZX518 busbar holder, provides a 40 mm busbar centre distance and accommodates a maximum of two copper busbars. The copper busbars are selected separately, allowing the module to be configured to suit the required distribution system.
The MBN269 occupies 2 panel widths (PW) and 1 grid unit (GU), corresponding to dimensions of 150 mm high × 500 mm wide × 200 mm deep with 24 space units (PLE). It is suitable for cabinets from 200 mm deep and can be installed using compatible EDF or WR mounting frames, which must be ordered separately.

Flexible N/PE Distribution with Horizontal Busbars
N/PE busbar modules provide dedicated distribution points for neutral and protective-earth conductors within low-voltage electrical assemblies. The ABB MBN269 provides a 2-pole horizontal arrangement for up to two copper busbars, helping create an organised and scalable N/PE distribution system within compatible CombiLine cabinets.
The module uses an ABB ZX518 busbar holder with a 40 mm centre distance and supports a maximum rated current of 320 A. Copper busbars are ordered separately, allowing their dimensions and current-carrying capability to be selected for the installation, while compatible modules of different widths can be combined with continuous busbars where required.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial sub-distribution systems.
- ABB CombiLine cabinet assemblies.
- Neutral conductor distribution.
- Protective-earth conductor distribution.
- Horizontal N/PE busbar systems.
- Electrical switchgear requiring modular N/PE distribution up to 320 A.
