Why Choose the ABB MBN175 N+PE / Terminal Expansion 1PW?
The ABB MBN175 is a modular N+PE / terminal expansion kit designed for ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine system and DESUJ Sub Distribution range, it combines provision for horizontal N/PE busbars with additional DIN rails for terminal blocks in a compact 1PW installation field.
The MBN175 is designed for a 2-pole horizontal busbar system and accommodates up to two copper busbars using ZX518 busbar holders. The busbars are ordered separately, while the terminal section incorporates two additional DIN rails that are continuously adjustable in depth using ZW59P2 depth-angle pieces.
Configured for 1 panel width (1PW), the MBN175 measures 450 × 250 × 200 mm and provides 36 space units. It offers 188 mm usable terminal width, an adjustable usable depth of 90–145 mm and a maximum rated current of 440 A.

Integrated N+PE and Terminal Distribution
The ABB MBN175 combines N/PE busbar distribution and terminal mounting within a single modular CombiLine field. Its horizontal two-pole busbar arrangement supports neutral and protective-earth distribution, while the two additional DIN rails provide dedicated space for organised terminal block installation.
The adjustable terminal mounting depth helps accommodate different terminal arrangements and wiring requirements. With a maximum rated current of 440 A and compatibility with EDF or WR mounting frames, the MBN175 provides a flexible internal expansion solution for low-voltage distribution assemblies.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- Neutral and protective-earth busbar distribution.
- Terminal block mounting and field wiring.
- Commercial and industrial electrical panels.
- Power distribution and control cabinets.
