1snk506411r0000 – zs4-sf-t2 [pk=50] fuse terminal block

Why Choose the TE Connectivity ZS4-SF-T2 Fuse Terminal Block?

The TE Connectivity ZS4-SF-T2 is a compact and reliable screw clamp fuse terminal block designed to combine DIN rail conductor termination with replaceable circuit protection in industrial control panels, machinery and automation systems. Part of the TE Connectivity ENTRELEC SNK terminal block series, it is designed for standard 5 × 20 mm fuses and provides convenient circuit protection within a space-saving 6 mm footprint.

The ZS4-SF-T2 features two integrated 2 mm test sockets, allowing convenient electrical testing without disturbing the connected conductors. Two jumper channels are aligned with compatible SNK feed-through and disconnect terminal blocks, helping simplify potential distribution and enabling organised terminal assemblies in professional control cabinets.

With an IEC current rating of 6.3 A and an IEC voltage rating of 500 V, the ZS4-SF-T2 provides dependable protection for control, instrumentation and auxiliary circuits. Its grey and dark-grey polyamide housing, screw clamp connections and compatibility with standard TH35 DIN rails make it well suited to demanding industrial panel-building applications.

Integrated Circuit Protection for Industrial Panels

Fuse terminal blocks combine electrical termination and overcurrent protection within a single DIN rail component. The ZS4-SF-T2 accepts a replaceable 5 × 20 mm fuse, allowing individual control and auxiliary circuits to be protected while maintaining an organised and serviceable terminal arrangement inside the electrical cabinet.

The ENTRELEC SNK platform is designed for modular panel construction, and the ZS4-SF-T2 incorporates two jumper channels for straightforward potential distribution alongside compatible SNK terminals. Integrated test sockets also enable technicians to perform measurements and troubleshooting efficiently without disconnecting the field wiring.

Typical Applications

• Industrial control panels and electrical cabinets.
• PLC input and output circuit protection.
• Machine building and OEM automation equipment.
• Instrumentation and process control systems.
• Protected auxiliary and signalling circuits.
• Motor control and distribution panels.
• Industrial electrical testing and maintenance systems.
