Why Choose the ABB ZX642 3-Pole Busbar Holder Adapter?
The ABB ZX642 2CPX046079R9999 is a purpose-designed 3-pole busbar holder intermediate piece for ABB Striebel & John high-current busbar systems. It is used with the ABB ZX640 3-pole busbar holder when constructing double-layer copper busbar arrangements in professional low-voltage switchgear assemblies.
The ZX642 is specifically required when installing 4 × 60 × 10 mm copper busbars. By providing the necessary intermediate spacing within the busbar holder assembly, it enables the ZX640 system to accommodate this double-layer conductor configuration while maintaining the intended mechanical arrangement.
Designed for 3-pole busbar systems, the ZX642 is associated with busbar arrangements rated up to 3500 A. It is supplied as 1 piece and integrates directly with the coordinated ABB ZX-series busbar support system.

Dedicated Support for Double-Layer Copper Busbars
High-current switchgear can require multiple copper conductors per phase to achieve the necessary current-carrying capacity. The ABB ZX642 provides the intermediate spacing required when the ZX640 3-pole busbar holder is configured with four 60 × 10 mm copper bars in a double-layer arrangement.
Using the dedicated ZX642 intermediate piece helps maintain the intended mechanical geometry of the ABB busbar support system. This coordinated approach is particularly important in high-current distribution assemblies where busbar alignment, spacing and mechanical support must be implemented consistently throughout the switchgear installation.
Typical Applications
- ABB ZX640 3-pole busbar holder assemblies.
- Double-layer 4 × 60 × 10 mm copper busbar systems.
- High-current low-voltage switchgear assemblies.
- Industrial main distribution switchboards.
- High-capacity electrical distribution panels.
- Commercial and industrial power distribution systems.
