TE Connectivity ZK4-PE push-in earth terminal block with 4 mm² conductor capacity and PI-Spring connection technology for reliable DIN rail protective earth connections.
£3.05
The TE Connectivity ZK4-PE (part number 1SNK706150R0000) is a reliable 4 mm² DIN rail mounted push-in earth terminal block designed for safe and efficient protective conductor connections in industrial electrical installations. As part of the TE Connectivity ENTRELEC SNK PI-Spring terminal block series, it provides a compact screwless solution for control panels, automation systems and power distribution applications.
This earth terminal uses a PI-Spring connection technology to provide secure, maintenance-friendly wiring without the need for screw tightening. The green-yellow housing provides clear protective earth identification, while the compact design enables efficient use of DIN rail space in modern electrical cabinets.
With a 4 mm² rated cross-section, 6 mm spacing and compatibility with TH35 DIN rails, the ZK4-PE is suitable for reliable grounding and equipotential bonding applications where fast installation and dependable electrical performance are required.
Earth terminal blocks provide an essential safety function by creating a reliable protective conductor connection between electrical equipment and the grounding system. The TE Connectivity ZK4-PE uses spring connection technology to maintain consistent contact pressure while reducing the risk of connection errors caused by incorrect tightening.
Designed for industrial automation and electrical control applications, the ZK4-PE combines compact DIN rail installation with robust mechanical and electrical performance. Its screwless design helps speed up panel assembly while supporting reliable long-term operation in demanding environments.
