1sna115914r0700 – d6/8.st.rs test circuit block

Why Choose the TE Connectivity D6/8.ST.RS Test Disconnect Terminal Block?

The TE Connectivity 1SNA115914R0700 D6/8.ST.RS is a 6 mm² spring-loaded screw-clamp test disconnect terminal block designed for circuit isolation, testing and measurement in industrial control and signal applications. Part of the established ENTRELEC terminal block range, it combines secure conductor termination with an accessible disconnect mechanism in a compact DIN rail format.

The D6/8.ST.RS uses a screwdriver-operated sliding link to open or close the electrical path through the terminal. This provides technicians with a practical test and isolation point without requiring the permanently connected conductors to be removed, making the terminal particularly useful during commissioning, diagnostics, maintenance and electrical measurements.

With a 6 mm² rated cross-section, 24 A IEC rated current and 400 V IEC operating voltage, the D6/8.ST.RS provides robust performance for industrial signal circuits. It also offers a 720 A short-time withstand current for 1 s, a 6 kV impulse withstand rating and conductor capacity up to 10 mm² for rigid stranded wiring.

Key Advantages

• Screwdriver-operated sliding disconnect link provides convenient circuit isolation and testing.
• Allows test circuits to be opened without removing permanently connected conductors.
• 24 A IEC current rating and 400 V IEC voltage rating support industrial signal applications.
• 720 A short-time withstand current for 1 s provides robust electrical performance.
• Accepts flexible conductors up to 6 mm² and rigid stranded conductors up to 10 mm².
• Compatible with G32, TH35-7.5 and TH35-15 DIN rails for flexible panel installation.

Accessible Circuit Isolation for Testing and Measurement

The D6/8.ST.RS provides a dedicated disconnect point within a DIN rail terminal assembly. Its screwdriver-operated sliding link allows the electrical connection between the two sides of the terminal to be opened when testing or isolation is required, while the field conductors remain securely terminated in their screw clamps.

This arrangement is useful in control, monitoring and measurement systems where technicians need convenient access to individual circuits during commissioning or fault finding. The combination of a 6 mm² rated wire size, 24 A IEC current rating and compact 8 mm spacing makes the D6/8.ST.RS a practical solution for organised and serviceable industrial test circuit assemblies.

Typical Applications

• Industrial test and measurement circuits.
• Control-panel signal circuit isolation.
• PLC and automation system wiring.
• Instrumentation and monitoring circuits.
• Machine control and process automation panels.
• Commissioning, diagnostics and maintenance test points.
