Why Choose the TE Connectivity ZK2.5-3P-YL PI-Spring Terminal Block?
The TE Connectivity 1SNK705067R0000 ZK2.5-3P-YL is a compact 3-position PI-Spring feed-through terminal block designed for fast, reliable conductor termination in industrial control and automation systems. Part of the TE Connectivity ENTRELEC SNK series, it uses PI-Spring connection technology to provide dependable spring-clamp retention while reducing the time required for panel wiring and maintenance.
With three connection positions connected within a single feed-through circuit, the ZK2.5-3P-YL is particularly useful where multiple conductors need to share a common electrical potential. Its compact 5.2 mm spacing helps maximise wiring density, while the yellow housing provides clear visual identification within organised DIN rail terminal assemblies.
The ZK2.5-3P-YL is rated at 24 A and 1000 V IEC and accommodates flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm² / 26–12 AWG. A polyamide housing, wide -55–110 °C operating temperature range and compatibility with standard TH35 DIN rails make it a versatile choice for machinery, control panels and industrial automation installations.

Fast, High-Density Wiring with PI-Spring Technology
PI-Spring terminal blocks use spring-force conductor retention to provide consistent electrical contact without conventional screw tightening. This technology is particularly useful in industrial control cabinets and machinery where rapid installation, high wiring density and resistance to vibration are important considerations.
The ZK2.5-3P-YL combines this connection technology with a three-position, single-circuit configuration, allowing three conductors to be connected at the same electrical potential within only 5.2 mm of DIN rail width. Its 1000 V IEC rating and broad conductor compatibility make it suitable for both power and signal distribution within compact industrial assemblies.
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.
