Reliable N and PE Distribution for CombiLine N Systems
Neutral and protective-earth busbars provide organised connection and distribution points within low-voltage switchboards. The ABB MBN169 provides a dedicated horizontal 2-pole arrangement for N and PE conductors, helping panel builders create structured and maintainable electrical distribution assemblies.
The module supports copper busbars including 12 × 5 mm and 20 × 5 mm sizes, with the latter supporting the module's maximum rated current of 320 A. Its compact 1PW format makes it particularly useful where efficient use of cabinet space is required.
Typical Applications
- ABB CombiLine N low-voltage distribution boards.
- Neutral and protective-earth busbar distribution.
- Commercial sub-distribution panels.
- Industrial switchboards and electrical cabinets.
- Modular panel-building systems.
- Expansion of compatible ABB N and PE distribution arrangements.
