1snk505314r0000 – zs4-sp-t2 [pk=50]switch terminal block

Why Choose the TE Connectivity ZS4-SP-T2 1SNK505314R0000 Switch Terminal Block?

The TE Connectivity ZS4-SP-T2 1SNK505314R0000 is a grey disconnect screw clamp terminal block with integrated test sockets from the ENTRELEC SNK series. Designed for industrial control, instrumentation and test circuits, it combines convenient circuit disconnection with two built-in 2 mm test sockets, allowing measurement and diagnostic operations to be carried out efficiently at the terminal strip.

The ZS4-SP-T2 uses a compact 5.2 mm spacing and provides 2 positions, 1 circuit and 1 level. Its screw clamp connections accommodate flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.2–4 mm². Mounting is compatible with standard TH35-7.5 and TH35-15 DIN rails, making the terminal straightforward to integrate into industrial control cabinets.

Rated at 18 A and 400 V IEC, the 1SNK505314R0000 provides a 6000 V impulse withstand voltage and 300 A short-time withstand current for 1 s. The grey polyamide housing provides IP20 protection and a UL 94 V-0 flammability rating, while the operating temperature range of -55 to +110 °C supports demanding industrial environments. The terminal blocks are supplied in a pack of 50.
