Why Choose the TE Connectivity ZS4-PE-R2 Screw Clamp Ground Terminal Block?
The TE Connectivity ZS4-PE-R2 1SNK506153R0000 is a compact green/yellow screw clamp ground terminal block designed for protective earth and grounding connections in industrial control panels, marshalling cabinets and automation systems. Part of the TE Connectivity ENTRELEC SNK Series, it combines proven screw clamp conductor termination with a screwless DIN rail ground connection for secure and efficient installation.
The ZS4-PE-R2 has a rated cross-section of 4 mm², provides two connection positions on a single level and occupies only 6 mm of DIN rail width. Its profile is designed to align with compatible ZS4-SF fuse, ZS4-S-R1 disconnect and ZS4-R2 feed-through terminal blocks, making it particularly suitable for organised marshalling and instrumentation assemblies.
With conductor capacities up to 4 mm², a short-time withstand current of 480 A for 1 s and an IEC impulse withstand voltage rating of 8,000 V, the ZS4-PE-R2 provides dependable grounding performance in demanding industrial environments. Its robust polyamide housing carries an IP20 protection rating and UL 94V-0 flammability classification.

Reliable Grounding for Industrial Control Systems
Protective earth terminal blocks provide a secure connection between equipment grounding conductors and the grounded DIN rail. The TE Connectivity ZS4-PE-R2 combines screw clamp conductor connections with a screwless rail connection, helping create an efficient and dependable grounding path within industrial electrical assemblies.
The ZS4-PE-R2 is particularly suited to marshalling cabinets and analogue circuit installations because its profile matches compatible ZS4-SF fuse, ZS4-S-R1 disconnect and ZS4-R2 feed-through terminal blocks. This allows different circuit functions to be arranged together while maintaining consistent terminal geometry, marking and wiring organisation.
Typical Applications
- Protective earth connections in industrial control panels.
- Marshalling cabinets and analogue circuit wiring.
- Process control and instrumentation systems.
- Machine building and factory automation equipment.
- Electrical distribution and switchgear assemblies.
- PLC and industrial control cabinets.
- High-density DIN rail terminal assemblies.
