Why Choose the TE Connectivity ZK10 PI-Spring Terminal Block?
The TE Connectivity ZK10 (1SNK710010R0000) is a high-performance grey PI-Spring feed-through terminal block designed for reliable power and signal connections in industrial control panels, machinery and electrical distribution systems. Part of the TE Connectivity ENTRELEC SNK Series, it combines spring-terminal connection technology with a compact DIN rail mounting format for efficient panel wiring.
The ZK10 provides a single-level, single-circuit feed-through connection with two positions and a 10 mm pitch. Its PI-Spring connection system supports fast, secure conductor termination while eliminating the routine tightening associated with conventional screw-clamp connections, making it particularly suitable for high-density industrial panel building and automation applications.
With an IEC voltage rating of 1000 V and an IEC current rating of 57 A, the ZK10 provides substantial electrical performance in a compact terminal format. It accepts flexible conductors from 0.5–10 mm² and rigid stranded conductors up to 16 mm², while its polyamide housing and wide -55 to 110 °C operating temperature range provide dependable service in demanding industrial environments.
