1SNK508418R0000 – 10mm Fuse Terminal 6.3x32mm ZS10-SF

Why Choose the TE Connectivity ZS10-SF 1SNK508418R0000 Fuse Terminal Block?

The TE Connectivity ZS10-SF 1SNK508418R0000 is a 10 mm² screw clamp fuse terminal block designed to combine secure conductor termination with individual circuit protection in industrial electrical installations. Part of the TE Connectivity ENTRELEC SNK Series, it is specifically designed for 6.3 × 32 mm (¼ × 1¼ in) cartridge fuses and provides a compact DIN rail solution for protected power, control and auxiliary circuits.

The ZS10-SF features a closed fuse-holder design and a compact 8 mm pitch, allowing fuse protection to be incorporated efficiently into terminal assemblies. Two jumper channels help simplify potential distribution across compatible SNK Series terminals, while the screw clamp connection accepts flexible and rigid stranded conductors from 0.5–10 mm².

With an IEC rated current of 10 A and an IEC rated voltage of 630 V, the ZS10-SF provides dependable performance for industrial fused circuits. Its grey and dark-grey polyamide housing, IP20 protection, UL 94V-0 flammability rating and broad -55 to +110 °C operating temperature range support reliable installation in demanding electrical panels and equipment.

Reliable 6.3 × 32 mm Fuse Protection for Industrial Circuits

Fuse terminal blocks integrate replaceable overcurrent protection directly into a DIN rail terminal assembly, reducing the need for separate fuse holders while keeping protected circuits accessible for servicing. The TE Connectivity ZS10-SF accommodates a standard 6.3 × 32 mm cartridge fuse and provides secure screw clamp termination for conductors up to 10 mm², making it suitable for higher-capacity control and auxiliary wiring.

The terminal's two jumper channels simplify distribution between compatible SNK Series terminals, while the 8 mm modular width helps minimise panel space requirements. The fuse is removable for replacement without disturbing the field wiring, supporting efficient commissioning and maintenance of protected industrial circuits.
