Why Choose the TE Connectivity ZS4-R2 1SNK506013R0000 Screw Clamp Terminal Block?

The TE Connectivity ZS4-R2 1SNK506013R0000 is a compact and reliable grey screw-clamp feed-through terminal block designed for industrial control panels, marshalling cabinets and electrical distribution systems. Part of the TE Connectivity ENTRELEC SNK series, it provides secure conductor termination in a space-efficient DIN-rail format.

The ZS4-R2 is specifically designed to simplify circuit distribution in marshalling applications. Its profile is aligned with compatible ZS4-SF fuse, ZS4-S-R1 disconnect and ZS4-PE-R2 protective-earth terminal blocks, allowing conductor entries, jumper channels and marking systems to remain aligned across mixed-function terminal assemblies.

With a rated cross-section of 4 mm², an IEC rated current of 32 A and an IEC rated voltage of 800 V, the ZS4-R2 provides dependable connectivity for power, control and signal wiring. Its closed-block construction requires no end section, while the 6 mm spacing helps create compact and organised DIN-rail terminal strips.

Efficient Circuit Distribution for Marshalling Cabinets

The ZS4-R2 is particularly suited to marshalling cabinets where multiple terminal functions must be installed in an organised and consistent arrangement. Its profile aligns with selected SNK-series fuse, disconnect and protective-earth terminals, maintaining common conductor-entry positions, jumper channels and marking locations across the terminal strip.

The screw-clamp connection provides secure and serviceable conductor termination, while the closed housing means an additional end section is not required. With only 6 mm of DIN-rail width per terminal, the ZS4-R2 supports compact terminal assemblies without sacrificing convenient wiring access.

Typical Applications

• Industrial marshalling cabinets.
• Control panels and automation cabinets.
• Electrical distribution and switchgear assemblies.
• PLC and instrumentation wiring.
• Power, control and signal circuit termination.
• Machine building and OEM electrical systems.
• Process control and factory automation equipment.
• Mixed-function DIN-rail terminal assemblies.
