The TE Connectivity 1SNA115237R1000 is an ENTRELEC M6/8.ST1 grey screw clamp test disconnect terminal block designed for signal, measurement and control circuits in industrial electrical panels. Part of the established TE Connectivity ENTRELEC SNA series, it combines a screwdriver-operated sliding disconnect link with two independent built-in test sockets for efficient circuit isolation, testing and maintenance.
The M6/8.ST1 features two integrated 4 mm test sockets, allowing compatible test plugs to be connected directly to the terminal without disturbing permanent field wiring. Its sliding disconnect link provides a controlled method of opening the circuit, making the terminal particularly useful for commissioning, diagnostics and measurement applications.
With an IEC rated current of 40 A, rated voltage of 630 V and nominal conductor size of 6 mm², the 1SNA115237R1000 delivers dependable electrical performance. Its 8 mm pitch, polyamide 6.6 housing and compatibility with G32, TH35-7.5 and TH35-15 DIN rails make it well suited to professional industrial panel construction.
Test disconnect terminals allow technicians to isolate and measure electrical circuits without dismantling permanent wiring. The M6/8.ST1 combines a sliding disconnect link with two independent test sockets, enabling test equipment to be connected directly while providing clear control over the circuit connection.
The integrated 4 mm test sockets are compatible with suitable 4 mm test plugs, while the screw clamp terminals securely accommodate industrial conductors. This combination makes the M6/8.ST1 particularly useful for commissioning, troubleshooting, instrumentation and routine maintenance tasks.
