1snk508422r0000 – zs10-sf-r3 fuse terminal

Why Choose the TE Connectivity ZS10-SF-R3 Fuse Terminal?

The TE Connectivity 1SNK508422R0000 ZS10-SF-R3 is a robust screw clamp fuse terminal block designed to combine secure conductor termination with convenient circuit protection in industrial electrical installations. As part of the TE Connectivity ENTRELEC SNK series, it accepts standard 6.3 × 32 mm cartridge fuses and provides a compact DIN rail solution for protecting control, automation and distribution circuits.

The ZS10-SF-R3 incorporates a red LED blown-fuse indicator for 115–250 V AC/DC circuits, enabling maintenance personnel to identify a failed fuse quickly during inspection and fault finding. The fuse is readily accessible for replacement while the terminal's screw clamp connections provide dependable conductor retention. The fuse itself is not supplied with the terminal block.

With a rated cross-section of 10 mm², compact 8 mm spacing and two connection positions, the ZS10-SF-R3 is suitable for conductors up to 10 mm² / 6 AWG. The terminal is rated at 10 A and 630 V IEC and supports DIN rail mounting on standard TH35 profiles, making it ideal for modular industrial control panel construction.

Integrated Circuit Protection for Industrial Panels

Fuse terminal blocks combine conductor termination and overcurrent protection within a single modular DIN rail component. This helps reduce panel complexity while allowing individual circuits to be protected and serviced without installing a separate panel-mounted fuse holder.

The ZS10-SF-R3 is designed around standard 6.3 × 32 mm cartridge fuses and includes an integrated red LED indicator for rapid identification of a blown fuse on 115–250 V AC/DC circuits. Its screw clamp connections and compact SNK-series format make it particularly suitable for industrial control, automation and distribution panels where reliable protection and straightforward maintenance are required.
