Why Choose the TE Connectivity ZS4-PE 1SNK505150R0000 Earth Terminal?
The TE Connectivity ZS4-PE 1SNK505150R0000 is a compact and reliable 4 mm² screw clamp earth terminal block designed to provide protective earth connections in industrial electrical panels, machinery and control systems. As part of the ENTRELEC SNK series, it combines a high-density terminal design with dependable screw connection technology for secure conductor termination.
Designed specifically for grounding applications, the ZS4-PE features the standard green and yellow protective earth colour and mounts directly onto commonly used TH35 DIN rails. Its single-level, two-position configuration provides a straightforward method of connecting protective conductors to the DIN rail and grounding system within an electrical enclosure.
The terminal supports flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.2–4 mm². With a compact 5.2 mm terminal spacing, polyamide housing and screw clamp termination, the ZS4-PE is well suited to space-conscious industrial control cabinets where secure and clearly identifiable protective earth connections are required.

Reliable Protective Earth Connections for Industrial Panels
Protective earth terminal blocks provide an organised and dependable connection between equipment protective conductors and the grounding system of an electrical installation. The TE Connectivity ZS4-PE is designed for this purpose, combining screw clamp termination with DIN rail mounting to create a robust protective earth connection within control cabinets and distribution assemblies.
The SNK series compact terminal format allows multiple terminal blocks to be installed efficiently along a DIN rail while maintaining clear conductor identification. The green/yellow ZS4-PE housing distinguishes the grounding connection from standard feed-through terminals, helping simplify panel assembly, inspection and maintenance.
Typical Applications
- Protective earth wiring in industrial control panels.
- Electrical switchboards and distribution assemblies.
- Machine control cabinets and automation equipment.
- Motor control centres and industrial machinery.
- DIN rail grounding and bonding systems.
- OEM electrical equipment and panel building.
