Why Choose the TE Connectivity ZK2.5-RD PI-Spring Terminal Block?
The TE Connectivity ZK2.5-RD, part number 1SNK705062R0000, is a compact and reliable PI-Spring feed-through terminal block designed for conductor connections in industrial control panels, machinery and electrical distribution systems. As part of the TE Connectivity ENTRELEC SNK Series, it combines space-efficient DIN rail installation with fast spring-clamp connection technology.
PI-Spring technology combines Push-In and spring connection methods to simplify wiring while maintaining dependable contact pressure. Solid conductors and suitably prepared stranded conductors can be inserted directly, while conventional stranded conductors can be connected using a screwdriver-assisted spring mode. This makes the ZK2.5-RD well suited to panel building and automation applications where installation speed and connection reliability are important.
With an IEC rated voltage of 1000 V, an IEC rated current of 24 A and compact 5.2 mm spacing, the ZK2.5-RD delivers high electrical performance while conserving valuable DIN rail space. Its distinctive red polyamide housing provides clear visual identification within terminal assemblies.
