Why Choose the TE Connectivity ZS16-PE 1SNK510150R0000 Earth Terminal Block?
The TE Connectivity ZS16-PE 1SNK510150R0000 is a robust 16 mm² green and yellow screw-clamp earth terminal block designed to provide reliable protective earth connections in industrial control panels, switchgear, machinery and power distribution equipment. Part of the TE Connectivity ENTRELEC SNK series, it combines secure screw-clamp conductor termination with an operator-independent rail contact for dependable connection to the DIN rail.
Designed specifically for protective earth applications, the ZS16-PE provides one circuit, one level and two connection positions. Its screwless rail-contact system helps improve installation safety in the event of a short circuit because the protective earth connection to the rail does not depend on the operator tightening an additional rail-contact screw.
With a rated cross-section of 16 mm², the ZS16-PE accepts flexible and rigid stranded conductors from 0.5–16 mm². Its 10 mm spacing, standard TH35 DIN-rail compatibility and green/yellow identification make it a practical protective-earth solution for organised and serviceable industrial terminal assemblies.

Dependable Protective-Earth Connection to the DIN Rail
Protective-earth terminal blocks provide a dedicated connection between field conductors and the grounded DIN rail. The ZS16-PE uses an operator-independent rail contact, helping ensure reliable earth continuity without requiring a separate rail-contact screw to be tightened during installation. This design supports safe and consistent protective-earth wiring in industrial electrical assemblies.
The ZS16-PE also provides a substantial 1920 A short-time withstand current for 1 s, supporting demanding protective-earth applications. Its green/yellow housing clearly distinguishes PE connections from standard feed-through circuits, while the 10 mm terminal spacing maintains a compact installation footprint for conductors up to 16 mm².
Typical Applications
