Why Choose the TE Connectivity ZK16-PE PI-Spring Ground Terminal Block?
The TE Connectivity ZK16-PE (1SNK712150R0000) is a heavy-duty PI-Spring protective earth terminal block designed to provide secure grounding connections between conductors and the DIN rail in industrial control panels, machinery and electrical distribution systems. Part of the ENTRELEC SNK Series, this green-and-yellow terminal combines high conductor capacity with a screwless rail contact engineered for dependable protective earth connections.
The ZK16-PE uses PI-Spring connection technology for fast and reliable conductor termination. Its protective earth design incorporates a screwless rail contact that is independent of operator tightening, helping provide consistent contact with the mounting rail. The terminal securely snaps onto and off compatible DIN rails and has a profile aligned with the corresponding ZK16 feed-through terminal for organised panel construction.
With a rated cross-section of 16 mm², the ZK16-PE accepts rigid conductors from 0.5–25 mm² and flexible conductors up to 16 mm². Its 12 mm spacing, two connection positions, IP20 construction and wide operating temperature range make it suitable for robust protective earth wiring in demanding industrial installations.

Reliable Protective Earth Connections for Industrial Installations
Protective earth terminal blocks provide an essential connection between equipment conductors and the grounded mounting rail. The ZK16-PE is specifically engineered for this role, using a screwless rail contact that does not depend on an installer applying a particular tightening torque. This helps provide consistent grounding performance while simplifying installation and maintenance.
The combination of PI-Spring conductor termination, high short-time withstand capability and conductor capacity up to 25 mm² for rigid wiring makes the ZK16-PE well suited to demanding industrial panels. Its green-and-yellow housing clearly identifies the protective earth function, while its profile alignment with ZK16 terminals supports clean, modular DIN rail assemblies.
