1snk505063r0000 – zs4-pr [pk=50] purple terminal block

Why Choose the TE Connectivity ENTRELEC ZS4-PR 1SNK505063R0000 Terminal Block?

The TE Connectivity ENTRELEC ZS4-PR 1SNK505063R0000 is a compact 4 mm² feed-through screw clamp terminal block designed for reliable conductor connections in control panels, distribution equipment and industrial automation systems. Part of the established ENTRELEC SNK Series, this version features a distinctive purple polyamide housing and provides two connection positions on a single level.

The ZS4-PR combines a space-saving 5.2 mm terminal pitch with conductor capacity up to 4 mm². Its screw clamp termination provides a secure and familiar connection method for industrial wiring, while DIN rail mounting allows straightforward integration alongside other SNK Series terminal blocks.

Rated at 32 A and 1000 V IEC, the 1SNK505063R0000 is engineered for demanding electrical applications. Its polyamide housing carries a UL 94V-0 flammability rating, while the terminal is specified for an operating temperature range of -55 to 110 °C, providing a robust solution for professional industrial wiring installations.

Reliable Screw Clamp Connections for Industrial Control Panels

Feed-through terminal blocks provide a convenient method of connecting conductors through control panels and electrical enclosures while maintaining an organised DIN rail installation. The TE Connectivity ENTRELEC ZS4-PR uses established screw clamp technology to create secure conductor connections, while its compact 5.2 mm pitch helps maximise connection density within electrical cabinets.

With conductor capacity up to 4 mm², a 32 A IEC current rating and 1000 V IEC voltage rating, the 1SNK505063R0000 is suitable for a broad range of power distribution, control and automation wiring. The purple housing also provides immediate visual differentiation within mixed-colour terminal assemblies where organised circuit or conductor identification is required.

Typical Applications

• Industrial electrical control panels.
• Machine building and OEM equipment.
• Automation and process control cabinets.
• Power distribution and feed-through wiring.
• DIN rail terminal assemblies.
• Motor control and switchgear panels.
• Colour-coded circuit and conductor identification.
