1snk508320r0000 – zs10-s-bl disconnect terminal

Why Choose the TE Connectivity ZS10-S-BL 1SNK508320R0000 Blue Disconnect Terminal Block?

The TE Connectivity ZS10-S-BL 1SNK508320R0000 is a compact screw clamp disconnect terminal block designed for reliable circuit isolation in industrial control panels, machinery, automation systems and electrical distribution equipment. Part of the ENTRELEC SNK series, this blue terminal combines secure screw clamp conductor termination with an integrated blade disconnect for convenient switching, testing and maintenance.

The ZS10-S-BL provides two connection positions, one circuit and one level within an 8 mm terminal spacing. Its blade disconnect allows the electrical path to be opened without removing the connected conductors, providing a defined isolation point for commissioning, troubleshooting and servicing industrial electrical circuits.

Rated at 25 A and 630 V to IEC specifications, the ZS10-S-BL accepts flexible conductors from 0.22–10 mm² and rigid stranded conductors from 0.2–10 mm². Its blue polyamide housing, DIN rail mounting and wide -55 to +110 °C operating temperature range provide a dependable solution for professional industrial wiring.
