Why Choose the ABB MN363 N+PE / Terminal Expansion 3PW?
The ABB MN363, order code 2CPX041292R9999, is an N/PE busbar and terminal expansion module designed for ABB CombiLine sub-distribution systems. Supplied as a mounted interior module for cabinet installation, it combines neutral and protective earth busbar provision with terminal mounting space, providing an organised solution for power distribution and termination within professional low-voltage electrical assemblies.
Designed for demanding distribution applications, the MN363 incorporates a 2-pole horizontal busbar system with an ABB ZX149 busbar holder and supports a maximum rated current of 630 A. It accommodates up to two copper busbars measuring 30 × 10 mm, which are ordered separately, and provides additional DIN rail space for terminal blocks.
The MN363 occupies 3 panel widths (PW) and 3 grid units (GU), with dimensions of 450 mm high × 750 mm wide × 260 mm deep and 108 space units (PLE). It provides a usable terminal width of 688 mm, while the mounting arrangement can be continuously adjusted in depth to provide a usable 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 MN363 combines a high-current 2-pole horizontal busbar arrangement with substantial terminal mounting space, allowing distribution and termination functions to be organised within one modular cabinet section.
As part of the ABB CombiLine system, the MN363 provides flexible integration into professional distribution cabinets. Its 688 mm usable width offers generous space for terminal equipment, while the continuously adjustable 90–145 mm usable depth helps accommodate different installation requirements. The 3-panel-width format makes the module particularly suitable for larger distribution assemblies requiring extensive N/PE and terminal capacity.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial sub-distribution systems.
- ABB CombiLine cabinet assemblies.
- Neutral and protective earth busbar distribution.
- Terminal block mounting and cable termination.
- Large electrical switchgear and distribution cabinets.
- Distribution assemblies requiring N/PE busbar currents up to 630 A.
