Why Choose the ABB ZX146 3-Pole Busbar Bracket?
The ABB ZX146 is a robust 3-pole busbar bracket designed to securely support copper busbars within ABB low-voltage sub-distribution assemblies. As part of the ABB DESUJ Sub Distribution range, it provides a purpose-designed mounting solution for three-phase busbar systems with a rated current of up to 630 A.
The ZX146 features a 60 mm busbar centre distance and accommodates copper rails ranging from 12 × 5 mm to 30 × 10 mm. This broad compatibility makes the bracket suitable for a range of busbar configurations used in modular power distribution systems and electrical cabinets.
With its 3-pole configuration, durable plastic construction and compact 180 × 60 × 17 mm format, the ZX146 provides reliable mechanical support for phase conductors while helping maintain consistent busbar spacing and an organised distribution assembly.

Reliable Busbar Support for Electrical Distribution
Busbar brackets such as the ABB ZX146 provide mechanical support and accurate positioning for phase conductors within low-voltage distribution assemblies. Maintaining consistent conductor spacing helps create structured busbar systems while providing secure support for the copper rails used to distribute substantial electrical currents throughout the installation.
The ZX146 is designed for ABB modular distribution systems and combines a 3-pole arrangement with compatibility across multiple copper rail dimensions. The related ZX147 single-pole bracket can be added in a row on the ZX146 where an additional conductor position is required within a compatible assembly.
Typical Applications
- Low-voltage sub-distribution boards.
- Three-phase copper busbar systems.
- Industrial electrical distribution cabinets.
- Commercial building distribution assemblies.
- Modular switchgear and panel-building systems.
- ABB CombiLine N and compatible sub-distribution installations.
