Reliable Electrical Connections for Copper Busbar Systems
Busbar connecting terminals provide an essential interface between electrical conductors and copper distribution rails in low-voltage electrical assemblies. They enable conductors to be connected to a common distribution system while supporting organised wiring arrangements within electrical panels and switchgear equipment.
The ABB ZK178P50 is specifically designed for conductors with cross-sectional areas from 16 mm² to 70 mm². Its compatibility with 5 mm thick copper busbars and integrated retaining spring allows the terminal to be mounted directly onto suitable copper rails without requiring a separate mounting bracket.
As part of the ABB STRIEBEL & JOHN busbar connection accessory range, the ZK178P50 supports efficient assembly of compatible CombiLine N distribution systems. The snap-on mounting arrangement simplifies terminal positioning, while the compact single-pole design makes it suitable for installations requiring multiple conductor connections. Electrical ratings, conductor compatibility, tightening requirements and installation clearances must be verified against the applicable ABB technical documentation and complete assembly design.
Typical Applications
- Low-voltage electrical distribution boards.
- Compatible ABB CombiLine N distribution systems.
- Copper busbar conductor connections.
- Industrial switchgear and power distribution panels.
- Commercial building electrical distribution installations.
- Electrical panel manufacturing and assembly.
