1snk705065r0000 – zk2.5-wh pi-spring clamp – white

Why Choose the TE Connectivity ZK2.5-WH 1SNK705065R0000 PI-Spring Terminal Block?

The TE Connectivity ZK2.5-WH 1SNK705065R0000 is a white PI-Spring feed-through terminal block from the ENTRELEC SNK Series, designed for fast and reliable DIN rail wiring in industrial control and automation systems. Its spring-clamp connection technology provides secure conductor termination without the conventional screw connection used by many terminal blocks.

With a compact 5.2 mm pitch, two positions, one circuit and a single-level configuration, the ZK2.5-WH helps create space-efficient terminal assemblies. It accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm², while ferrules can also be accommodated for professionally prepared panel wiring.

The terminal provides an IEC current rating of 24 A and an IEC voltage rating of 1000 V, together with an 8000 V impulse withstand rating. Its polyamide housing, IP20 rating, UL 94V-0 flammability classification and -55 to +110 °C operating temperature range support dependable use in demanding industrial environments.

Reliable PI-Spring Connections for Efficient Panel Wiring

The PI-Spring connection system provides a practical alternative to traditional screw terminals by using spring force to maintain conductor contact. This helps streamline panel wiring while providing consistent conductor retention. The ZK2.5-WH accommodates flexible conductors up to 2.5 mm² and rigid stranded conductors up to 4 mm², making it suitable for a broad range of control and power wiring requirements.

Its 5.2 mm modular pitch allows dense terminal arrangements without sacrificing electrical performance, while the 24 A IEC current rating and 1000 V IEC voltage rating provide strong capability for its compact size. Standard DIN rail mounting makes the terminal straightforward to integrate with other ENTRELEC SNK Series components.
