1snk508421r0000 – zs10-sf-r1 fuse terminal

Why Choose the TE Connectivity ZS10-SF-R1 1SNK508421R0000 Fuse Terminal Block?

The TE Connectivity ZS10-SF-R1 1SNK508421R0000 is a 10 mm² screw clamp fuse terminal block designed to combine secure conductor termination with replaceable circuit protection and visual fault indication. Part of the TE Connectivity ENTRELEC SNK Series, it accepts standard 6.3 × 32 mm (¼ × 1¼ in) cartridge fuses and is suited to protected control, auxiliary and industrial electrical circuits.

The ZS10-SF-R1 incorporates a red LED blown-fuse indicator for 24–110 V AC/DC circuits, helping maintenance personnel identify an operated fuse quickly without extensive troubleshooting. Its compact 8 mm pitch supports space-efficient DIN rail assemblies, while the two-position, single-level configuration provides a straightforward fused connection within modular control-panel wiring.

Rated at 10 A and 630 V IEC, the ZS10-SF-R1 accepts flexible and rigid stranded conductors up to 10 mm² / 6 AWG. Its grey and dark-grey polyamide construction, IP20 protection, UL 94V-0 flammability rating and broad -55 to +110 °C operating temperature range support reliable use in demanding industrial installations.

Reliable Fuse Protection with Visual Fault Indication

Fuse terminal blocks integrate replaceable overcurrent protection directly into the DIN rail terminal assembly, keeping protected circuits compact and accessible for maintenance. The TE Connectivity ZS10-SF-R1 accepts a standard 6.3 × 32 mm fuse and combines this protection function with screw clamp termination for conductors up to 10 mm².

The integrated red LED blown-fuse indicator is designed for 24–110 V AC/DC circuits and provides immediate visual assistance when a fuse has operated. This combination of fused protection, fault indication and an 8 mm modular profile makes the ZS10-SF-R1 particularly useful where rapid troubleshooting, serviceability and efficient panel space utilisation are important.
