Why Choose the ABB MBN162 N+PE / Terminal Expansion 1PW?
The ABB MBN162 is a CombiLine N N+PE busbar and terminal expansion module designed for structured neutral, protective-earth and terminal distribution within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041758R9999, it forms part of the ABB DESUJ Sub Distribution product group and combines provision for N/PE copper busbars with a DIN rail for terminal blocks.
Designed for a compact 1-panel-width (1PW) configuration, the MBN162 is 300 mm high × 250 mm wide and provides 24 space units. The module incorporates one additional DIN rail for terminal blocks together with a 2-pole horizontal N/PE busbar system using ABB ZX149 busbar holders and supporting a maximum of two copper rails.
The MBN162 supports a maximum rated current of 630 A and a short-time withstand current of 20 kA. Its DIN rail is steplessly adjustable in depth, providing approximately 90–145 mm usable depth and 188 mm usable terminal width. Copper busbars and the mounting frame are ordered separately, while the closed RAL 7035 plastic cover provides a protected finished installation.
Key Advantages

Compact N+PE Busbar and Terminal Distribution up to 630 A
The ABB MBN162 combines two important distribution functions within a single compact cabinet field: a 2-pole horizontal copper busbar system for neutral and protective-earth distribution and an additional DIN rail for terminal blocks. The ZX149 busbar holder arrangement supports up to two copper rails, while the module's 630 A maximum rated current makes it suitable for substantial low-voltage distribution duties despite its compact 1PW footprint.
For terminal wiring, the MBN162 provides approximately 188 mm usable width, while the DIN rail can be adjusted steplessly to provide approximately 90–145 mm usable depth. This combination allows the termination area to be adapted to different terminal blocks and wiring arrangements while maintaining an organised CombiLine N cabinet layout.
Typical Applications
- ABB CombiLine N low-voltage distribution cabinets.
- Neutral and protective-earth busbar distribution.
- Terminal block and field wiring installations.
- Commercial and industrial sub-distribution boards.
- Compact N/PE distribution applications up to 630 A.
- Professional panel-building and system integration projects.
