Why Choose the ABB ZK79P5 1.5–16 mm² Connecting Terminal?
The ABB ZK79P5 Connecting Terminal is a professional electrical connection accessory designed for attaching conductors to compatible copper busbars in low-voltage distribution assemblies. Supplied as a pack of 5 connecting terminals, the ZK79P5 supports conductor cross-sections from 1.5 mm² to 16 mm² and is intended for copper rails with a 5 mm thickness.
Identified by ABB order code 2CPX062631R9999, this product belongs to the ABB DESUJ Sub Distribution product group and is included in the ABB Striebel & John CombiLine N interior expansion system. Its design incorporates a retaining spring, allowing the connecting terminal to latch onto a compatible copper rail and provide a dedicated connection point for the specified conductor range.
The ABB ZK79P5 is particularly useful for electrical contractors, switchboard manufacturers and maintenance engineers working with copper busbar distribution systems. The five-piece packaging provides a convenient quantity for installations requiring several matching connection points, while the defined conductor range helps installers select the appropriate terminal for their electrical assembly.

Reliable Conductor Connections for 5 mm Copper Busbars
Copper busbar systems are widely used in electrical distribution assemblies to provide organised current distribution between electrical devices and circuits. Correctly selected connecting terminals allow conductors to be attached to the busbar system while maintaining the intended electrical and mechanical connection arrangement.
The ABB ZK79P5 is designed specifically for 5 mm thick copper rails and a conductor connection range of 1.5–16 mm². Its retaining spring allows the terminal to latch onto the compatible rail, providing a practical method of positioning the connecting terminal within the intended ABB busbar arrangement.
The defined connection range is an important selection characteristic. Conductors smaller than 1.5 mm² or larger than 16 mm² fall outside the specified range and should not be used without explicit manufacturer approval. Installers must also verify the permitted conductor construction, connection method, tightening requirements and electrical rating using the applicable ABB technical instructions.
Integration into ABB CombiLine N Distribution Systems
The ABB ZK79P5 forms part of the CombiLine N interior expansion system, a range of accessories used in electrical distribution board construction. Within suitable copper busbar configurations, the connecting terminal provides a dedicated point for attaching conductors to the distribution rail.
The latching design with retaining spring is intended to simplify positioning on the specified copper rail. This can be particularly useful when assembling multiple busbar connections or replacing matching terminals during electrical distribution board maintenance.
For correct installation, the copper rail dimensions, conductor cross-section, conductor preparation and complete electrical assembly must match the relevant ABB documentation. The terminal's conductor size range alone does not establish the permissible operating current or short-circuit rating of the completed connection.
ABB ZK79 Connecting Terminal Pack Options
The ZK79 connecting terminal is available in several manufacturer-listed packaging quantities, allowing installers to select a suitable quantity for their project:
- ABB ZK79: Single connecting terminal, order code 2CPX064879R9999.
- ABB ZK79P4: Pack of 4 connecting terminals, order code 2CPX062421R9999.
- ABB ZK79P5: Pack of 5 connecting terminals, order code 2CPX062631R9999.
- ABB ZK79P50: Pack of 50 connecting terminals, order code 2CPX062429R9999.
These ZK79 variants share the manufacturer-listed 1.5–16 mm² conductor range and 5 mm copper rail compatibility. The principal distinction between these listed variants is the supplied quantity.
