Why Choose the TE Connectivity ZK2.5-3P-GN PI-Spring Terminal Block?
The TE Connectivity 1SNK705068R0000 ZK2.5-3P-GN is a compact 3-position PI-Spring feed-through terminal block designed for fast and reliable conductor termination in industrial control, automation and machinery applications. Part of the TE Connectivity ENTRELEC SNK series, it combines spring-clamp connection technology with a space-efficient DIN rail format for high-density panel wiring.
The ZK2.5-3P-GN provides three connection positions within one electrical circuit, allowing three conductors to share a common potential without requiring an additional external jumper. Its compact 5.2 mm spacing helps minimise DIN rail usage, while the green polyamide housing provides clear visual identification within organised terminal assemblies.
Rated at 24 A and 1000 V IEC, the ZK2.5-3P-GN accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm² / 26–12 AWG. With IP20 protection, UL 94V-0 flammability performance and a wide -55–110 °C operating temperature range, it is well suited to professional industrial panel building and OEM electrical systems.

Fast, Space-Efficient Wiring with PI-Spring Technology
PI-Spring terminal blocks use spring-force conductor retention to provide consistent electrical contact while reducing the need for conventional screw-tightening operations. This makes them particularly suitable for industrial control panels and machinery where fast installation, compact wiring and dependable connections are important.
The ZK2.5-3P-GN combines this technology with a three-position, single-circuit configuration, enabling three conductors to share the same potential within only 5.2 mm of DIN rail width. Its 24 A current rating, 1000 V IEC voltage rating and broad conductor compatibility make it a versatile solution for both power and signal distribution.
Typical Applications
- Industrial electrical control panels.
- PLC and automation system wiring.
- Three-conductor common-potential connections.
- Machine building and OEM electrical systems.
- Process control and instrumentation panels.
- Power and signal distribution circuits.
- High-density DIN rail terminal assemblies.
- Industrial machinery and equipment cabinets.
