1snk505313r0000 – 4mm disconnect terminal grey [pk=50]

Why Choose the TE Connectivity ZS4-SP 1SNK505313R0000 Grey Disconnect Terminal Block?

The TE Connectivity ZS4-SP 1SNK505313R0000 is a grey 4 mm² disconnect screw clamp terminal block from the ENTRELEC SNK series, designed for circuits that require a convenient means of electrical isolation while maintaining an organised DIN rail terminal assembly. Its compact 5.2 mm spacing makes it particularly suitable for control panels, instrumentation systems and industrial automation equipment where wiring density and straightforward circuit access are important.

The ZS4-SP combines a 2-position, single-circuit, single-level configuration with established screw clamp connection technology. It accepts flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.2–4 mm², while mounting directly onto standard TH35-7.5 and TH35-15 DIN rails.

Rated at 18 A and 400 V IEC, the 1SNK505313R0000 provides a 6000 V impulse withstand rating and a short-time withstand current of 300 A for 1 s. Its durable grey polyamide housing offers IP20 protection and a UL 94 V-0 flammability rating, while the -55 to +110 °C operating temperature range supports demanding industrial environments. This product is supplied in a pack of 50.
