Why Choose the ABB MN374 N+PE Terminal Expansion Module?
The ABB MN374, order code 2CPX041283R9999, is a mounted N+PE busbar and terminal expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a structured solution for integrating neutral and protective earth busbars together with terminal blocks into sub-distribution cabinets.
The MN374 is configured for a 2-pole N+PE busbar system with horizontal busbar alignment and includes ABB ZX518 busbar holders for a maximum of two copper busbars. An additional DIN rail provides mounting space for terminal blocks, while its depth-adjustable construction allows the internal assembly position to be adapted to suit the distribution cabinet installation.
With a module height of 2 GU / 300 mm, a panel width of 3 PW / 750 mm and 72 space units, the MN374 provides a usable terminal width of 688 mm. It supports a maximum rated current of 440 A and is suitable for installation in cabinets from 200 mm depth.

Reliable N+PE Distribution for Electrical Cabinets
N+PE busbar modules provide an organised connection point for neutral and protective earth conductors within electrical distribution systems. The ABB MN374 combines a two-pole busbar arrangement with terminal mounting space, helping panel builders create structured and accessible conductor distribution within CombiLine cabinets.
The MN374 uses horizontally arranged busbars with ZX518 holders and accommodates up to two copper rails, which are ordered separately. Its additional DIN rail is continuously adjustable in depth, providing flexibility when positioning terminal blocks and wiring within the available cabinet space.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine cabinet assemblies.
- Neutral and protective earth conductor distribution.
- Commercial and industrial electrical installations.
- Terminal block expansion within distribution cabinets.
- Panel building and electrical switchgear installations.
