Why Choose the ABB ZB5 Busbar Holder?
The ABB ZB5 (2CPX038459R9999) is a professional 5-pole busbar holder designed for supporting copper busbars within compatible ABB electrical distribution systems. Part of the ABB DESUJ Sub Distribution product group, it provides a secure and accurately spaced mounting point for constructing organised low-voltage busbar assemblies.
The ZB5 provides a fixed 40 mm busbar centre distance and is suitable for copper busbars measuring 12 × 5 mm, 12 × 10 mm and 20 × 5 mm. Its five-pole configuration supports multi-conductor distribution arrangements while maintaining consistent spacing between the individual busbars.
Designed for a rated current of 360 A, the ZB5 is suitable for demanding power-distribution applications within compatible ABB CombiLine N and TriLine-R systems. The holder is supplied individually as 1 piece and can be combined with compatible ABB busbar accessories, including the ZX172 end cover.

Secure 5-Pole Busbar Support for Electrical Distribution Systems
Busbar holders provide the mechanical support and defined spacing required to construct orderly power-distribution assemblies. The ABB ZB5 securely supports five copper busbars with a 40 mm centre distance, helping maintain consistent alignment throughout compatible busbar systems while supporting rated currents up to 360 A.
Compatibility with three common copper busbar dimensions gives panel builders flexibility when configuring distribution assemblies. Used with suitable ABB system components and accessories, the ZB5 provides a practical foundation for constructing professional multi-pole busbar arrangements in compatible CombiLine N and TriLine-R installations.
