2CPX041291R9999 ABB MN263 N+PE / Terminal Expansion 2PW 630 A
ABB MN263 2CPX041291R9999 is a 2-panel-width CombiLine N N/PE busbar and terminal expansion module rated up to 630 A with a 2-pole horizontal busbar system and two additional DIN rails.
Why Choose the ABB MN263 N+PE / Terminal Expansion 2PW?
The ABB MN263, order code 2CPX041291R9999, is a N/PE busbar and terminal expansion module designed for ABB CombiLine N sub-distribution systems. Supplied mounted and installed for cabinet integration, it combines provision for neutral and protective earth busbars with additional DIN rails for terminal blocks, providing an organised solution for power distribution and termination within low-voltage electrical assemblies.
Designed for professional electrical distribution applications, the MN263 supports a 2-pole horizontal busbar system with a maximum rated current of 630 A. It incorporates the ABB ZX149 busbar bracket and accommodates a maximum of two copper busbars, which are ordered separately. Two additional DIN rails provide dedicated mounting space for terminal blocks, helping create a structured and accessible cabinet layout.
The MN263 occupies 2 panel widths (PW) and 3 grid units (GU), corresponding to nominal dimensions of 450 mm high × 500 mm wide and 72 space units (PLE). The terminal area provides a usable width of 438 mm, while the DIN rail can be continuously adjusted in depth to provide a usable depth range of 90–145 mm. The module is suitable for cabinets from 275 mm deep.

Reliable N/PE Distribution and Terminal Expansion
N/PE busbar modules provide dedicated infrastructure for neutral and protective earth distribution within low-voltage electrical assemblies. The ABB MN263 combines a 2-pole horizontal busbar arrangement with dedicated DIN rail space for terminal blocks, allowing distribution and termination functions to be organised within a single modular cabinet section.
The MN263 is designed around ABB's modular CombiLine N system and provides flexibility when configuring larger distribution assemblies. Its two additional DIN rails are continuously adjustable in depth using the mounting arrangement, while the 438 mm usable terminal width provides substantial space for terminal equipment. Continuous busbars can also be used across different module widths within compatible cabinet configurations.
