2CPX041284R9999 ABB MN175 N+PE Terminal Expansion Module 1PW

Why Choose the ABB MN175 N+PE Terminal Expansion Module?

The ABB MN175, order code 2CPX041284R9999, 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 neutral and protective earth busbars together with terminal blocks in professional sub-distribution cabinet installations.

The MN175 is designed for a 2-pole N+PE busbar system with horizontally arranged busbars and ABB ZX518 busbar holders for a maximum of two copper busbars. It also incorporates two additional DIN rails for terminal blocks, providing greater terminal capacity while maintaining an organised and accessible cabinet layout.

With a module height of 3 GU / 450 mm, a panel width of 1 PW / 250 mm and 36 space units, the MN175 provides a usable terminal width of 188 mm. Its DIN rail arrangement is continuously adjustable in depth from 90–145 mm, while the module supports a maximum rated current of 440 A and is suitable for cabinets from 200 mm depth.

Reliable N+PE Distribution for Electrical Cabinets

N+PE busbar modules provide organised connection points for neutral and protective earth conductors within electrical distribution systems. The ABB MN175 combines a two-pole busbar arrangement with dedicated terminal mounting space, helping panel builders create structured, accessible and maintainable conductor distribution within CombiLine cabinets.

The MN175 uses horizontally arranged busbars with ZX518 holders and accommodates up to two copper rails, which must be ordered separately. Its two additional DIN rails provide increased capacity for terminal blocks, while the continuously adjustable mounting depth allows the terminal arrangement to be positioned between 90 mm and 145 mm to suit the cabinet installation.

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.
