The TE Connectivity 1SNK508315R0000 ZS10-S is a robust screw clamp disconnect terminal block designed for convenient circuit isolation, testing and maintenance in industrial electrical installations. As part of the TE Connectivity ENTRELEC SNK series, it combines dependable screw clamp conductor termination with an integrated blade disconnect mechanism for control panels, switchgear, machinery and automation systems.
The ZS10-S features a blade disconnect operated by hand or with a screwdriver, allowing the electrical circuit to be opened without removing the connected conductors. Its profile is aligned with the ZS10 feed-through terminal block, helping engineers maintain consistent marking and use identical end-section accessories across mixed terminal assemblies.
With a compact 8 mm terminal spacing, two connection positions and an IEC rating of 25 A at 630 V, the ZS10-S provides reliable circuit isolation while supporting conductors up to 10 mm² / 6 AWG. Its grey polyamide housing, IP20 protection and wide -55–110 °C operating temperature range make it suitable for demanding industrial environments.
Disconnect terminal blocks provide a practical method of opening an electrical circuit directly at the terminal point without removing permanently connected conductors. This makes circuit testing, commissioning, fault finding and maintenance more efficient while preserving an organised and secure DIN rail wiring installation.
The ZS10-S combines a convenient blade disconnect with high-capacity screw clamp connections. The disconnect blade can be operated manually or with a screwdriver, while its profile alignment with the ZS10 feed-through terminal enables consistent marking and common end-section use across mixed terminal block assemblies.
