Why Choose the ABB ZK81P50 4–35mm² Connecting Terminal?
The ABB ZK81P50 is a professional single-pole busbar connecting terminal designed for connecting electrical conductors to copper busbars in low-voltage distribution boards and electrical control cabinets. Identified by ABB order code 2CPX062431R9999, this accessory belongs to the ABB DESUJ Sub Distribution product group and forms part of the ABB Striebel & John range of electrical distribution and busbar connection accessories.
Designed for reliable conductor termination, the ZK81P50 accommodates conductor cross-sections from 4–35 mm² and is suitable for 5 mm thick copper busbars. Its snap-on mounting design incorporates a retaining spring, allowing the terminal to be secured to compatible copper rails without requiring a separate mounting bracket. This provides a practical solution for panel builders and electrical installers who require organised busbar connections.
Supplied as a pack of 50 connecting terminals, the ABB ZK81P50 is suitable for compatible copper busbars with widths of 12–30 mm. Its compact terminal design, with a clamp width of 15.5 mm, supports efficient use of available space in electrical distribution assemblies. The product is particularly useful for electrical contractors, switchboard manufacturers and maintenance engineers working with ABB CombiLine N and compatible busbar systems.

Reliable Electrical Connections for Copper Busbar Systems
Copper busbars are widely used in electrical distribution assemblies to provide an organised and efficient method of distributing electrical power. Reliable connections between conductors and busbars are essential for maintaining electrical continuity and supporting safe operation. The ABB ZK81P50 connecting terminal provides a dedicated connection interface for round conductors with cross-sections from 4–35 mm².
The ZK81P50 features a snap-on retaining spring mechanism designed for mounting directly onto compatible 5 mm thick copper rails. This arrangement simplifies terminal positioning during electrical panel construction and provides a convenient method of attaching conductor connection points to the busbar system. Its single-pole configuration allows individual electrical connections to be arranged according to the requirements of the distribution assembly.
As part of the ABB CombiLine N interior expansion system, the ZK81P50 supports professional switchboard construction and electrical distribution applications. The 50-piece pack is particularly convenient for panel manufacturers and electrical contractors completing multiple installations. Correct conductor preparation, tightening torque, electrical ratings and busbar compatibility should be verified against the applicable ABB installation instructions before energising the assembly.
