Why Choose the TE Connectivity ZS4-T3-R1 1SNK506213R0000 Three-Level Terminal Block?

The TE Connectivity ZS4-T3-R1 1SNK506213R0000 is a compact three-level screw clamp feed-through terminal block designed for high-density industrial wiring applications. Part of the TE Connectivity ENTRELEC SNK series, it combines three independent feed-through circuits within a single DIN rail terminal block, providing six connection positions while helping reduce the amount of rail space required in control panels and electrical cabinets.

The ZS4-T3-R1 uses proven screw clamp connection technology to provide secure conductor termination across all three levels. Each level forms an independent feed-through circuit, making the terminal particularly useful for multi-conductor control, signal and power wiring where several circuits need to be accommodated within a compact panel footprint.

With a rated cross-section of 4 mm², an IEC current rating of 32 A and an IEC voltage rating of 800 V, the ZS4-T3-R1 provides dependable electrical performance for industrial installations. Its 6 mm terminal spacing, grey polyamide housing and TH35 DIN rail compatibility make it a practical solution for professional panel building and machine wiring.

High-Density Three-Level Connections for Industrial Panels

Three-level terminal blocks allow multiple independent circuits to be connected vertically within a single DIN rail position. By accommodating three separate feed-through circuits in one terminal block, they can significantly increase wiring density while keeping connections organised and accessible for installation, inspection, testing and maintenance.

The ZS4-T3-R1 provides three levels, three independent circuits and six connection positions within a 6 mm wide footprint. Combined with its 32 A IEC current rating, 800 V IEC voltage rating and conductor capacity up to 4 mm², this makes it particularly useful for densely populated industrial control cabinets where efficient use of DIN rail space is important.

Typical Applications

• High-density industrial control panels and electrical cabinets.
• PLC input, output and control circuit wiring.
• Machine building and OEM automation systems.
• Process control and instrumentation installations.
• Switchgear and electrical distribution assemblies.
• Factory automation and production machinery.
