Why Choose the TE Connectivity ZK4 1SNK706010R0000 PI-Spring Terminal Block?
The TE Connectivity ZK4 1SNK706010R0000 is a compact and reliable 4 mm² PI-Spring feed-through terminal block designed for power and signal wiring in industrial control panels, electrical enclosures and automation systems. As part of the ENTRELEC SNK series, it combines push-in and spring connection technology to provide fast installation and dependable conductor termination.
The ZK4 uses PI-Spring technology to provide two convenient wiring methods in a single terminal block. Solid conductors and stranded conductors fitted with ferrules can be connected using direct push-in insertion, while the spring mode allows straightforward connection of non-prepared stranded conductors using a screwdriver. This flexible design helps reduce wiring time while maintaining a secure electrical connection.
With a nominal 4 mm² conductor capacity, 32 A IEC current rating and 1000 V IEC voltage rating, the ZK4 is suitable for a wide range of industrial power and signal circuits. Its compact 6 mm terminal spacing, grey polyamide housing and compatibility with standard DIN rails make it particularly suitable for densely populated control cabinets.

Fast and Reliable PI-Spring Connections
PI-Spring technology combines the installation speed of push-in wiring with the versatility of a conventional spring connection. Suitable conductors can be inserted directly into the terminal, while a screwdriver can be used to operate the spring when connecting or removing other conductor types. This makes the ZK4 well suited to panel building, machine wiring and other applications where efficient assembly is important.
The spring connection maintains consistent contact pressure without requiring routine screw tightening. Combined with the compact 6 mm pitch and DIN rail mounting format, the ZK4 provides an efficient solution for organising power and signal wiring in industrial electrical cabinets.
Typical Applications
- Industrial control panels and electrical cabinets.
- Machine building and OEM automation systems.
- PLC and industrial control wiring.
- Power and signal distribution circuits.
- Factory automation and production machinery.
- DIN rail electrical installations.
