Why Choose the TE Connectivity ZK10-PE PI-Spring Earth Terminal?
The TE Connectivity ZK10-PE, part number 1SNK710150R0000, is a high-performance PI-Spring protective earth terminal block designed for reliable grounding connections in industrial control panels, machinery and electrical distribution systems. Part of the TE Connectivity ENTRELEC SNK Series, it combines screwless spring termination with a robust DIN rail earth connection.
The ZK10-PE uses PI-Spring technology to provide fast and dependable conductor termination while its dedicated ground function connects the protective earth circuit directly to the mounting rail. The screwless rail contact is designed to provide a secure connection independently of operator tightening, while the green and yellow housing clearly identifies the terminal as a protective earth connection.
Designed around a 10 mm² rated cross-section, the ZK10-PE accepts flexible conductors from 0.5–10 mm² and rigid stranded conductors from 0.5–16 mm². Its 10 mm spacing, 1200 A short-time withstand current for 1 s and compatibility with TH35 DIN rails make it a dependable grounding solution for demanding industrial power and signal installations.
