Reliable Three-Conductor PI-Spring Connectivity
The TE Connectivity ZK2.5-3P-BK extends the functionality of the ZK2.5 terminal platform by providing three conductor connection positions within one compact terminal. This arrangement is useful for distributing or branching a common electrical potential without installing an additional terminal and jumper arrangement.
PI-Spring technology provides consistent spring contact pressure while supporting efficient wiring, and the narrow 5.2 mm footprint helps conserve DIN rail space. With a 24 A IEC current rating, 1,000 V IEC voltage rating and support for rigid stranded conductors up to 4 mm², the ZK2.5-3P-BK is well suited to compact industrial control and distribution systems.
Typical Applications
- Industrial control panels and automation cabinets.
- Three-conductor distribution and branching circuits.
- PLC and I/O wiring systems.
- Power and signal distribution.
- Machine building and factory automation.
- Process control and instrumentation systems.
- High-density DIN rail terminal assemblies.
