Why Choose the ABB MN262 N+PE / Terminal Expansion?
The ABB MN262 is a factory-assembled CombiLine N+PE busbar and terminal expansion module designed for compatible ABB sub-distribution cabinets. Supplied under ABB order code 2CPX041288R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a 2 PW / 500 mm field width.
The MN262 has a 2 RE / 300 mm module height and provides 48 space units. It combines a horizontal N+PE busbar system with an additional DIN rail for terminal blocks, providing structured neutral, protective-earth and terminal connection capacity within professional distribution assemblies.
The module supports a 2-pole horizontal busbar system with a maximum of two copper busbars, uses a ZX149 busbar holder and is rated up to 630 A. The terminal installation area provides 438 mm usable width, while its DIN rail is continuously adjustable in depth to provide a usable range of 90–145 mm.
Key Advantages
- Combines N+PE busbar distribution and terminal installation in one module.

Integrated N+PE Busbar and Terminal Distribution
The ABB MN262 combines neutral and protective-earth busbar accommodation with dedicated terminal installation space in a single CombiLine module. Its horizontal 2-pole arrangement accommodates up to two copper busbars and supports a maximum rated current of 630 A, providing a structured connection area within compatible sub-distribution cabinets.
An additional DIN rail provides dedicated terminal-block mounting capacity across a usable width of 438 mm. The rail can be continuously adjusted in depth from 90–145 mm, allowing the terminal installation to be adapted to different equipment and wiring requirements while maintaining an organised distribution-board layout.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine distribution systems.
- Neutral and protective-earth busbar distribution.
- Terminal-block connection sections.
- Commercial and industrial electrical panels.
- Distribution-board extensions and structured connection areas.
