1sna105142r2000 – m 6/8 stpa2

Why Choose the TE Connectivity 1SNA105142R2000 M6/8.STP Disconnect Terminal Block?

The TE Connectivity 1SNA105142R2000 M6/8.STP, also referenced as M 6/8 STPA2, is a grey and red screw-clamp disconnect terminal block from the ENTRELEC SNA series, designed for convenient circuit isolation, testing and measurement in industrial control and automation systems. Its integrated push-turn disconnect mechanism allows an individual circuit to be opened without removing the connected conductors, simplifying commissioning, diagnostics and maintenance.

The M6/8.STP uses a ¼-turn push-turn knob for fast disconnect operation and can be sealed in the open position when required. The design also incorporates two 4 mm test sockets, providing convenient access for suitable test equipment while maintaining secure screw-clamp conductor connections.

With a nominal conductor cross-section of 6 mm², an IEC rating of 15 A at 500 V and compact 8 mm spacing, the 1SNA105142R2000 provides robust performance in space-conscious industrial panels. It accepts rigid conductors from 0.5–10 mm² and flexible conductors from 0.5–6 mm², while supporting G32, TH35-7.5 and TH35-15 DIN rail mounting.

Convenient Circuit Isolation and Electrical Testing

Disconnect terminal blocks allow individual circuits to be isolated while leaving the field conductors securely terminated. The M6/8.STP combines screw-clamp connections with a ¼-turn push-turn disconnect mechanism, providing technicians with a practical way to open circuits during commissioning, troubleshooting and scheduled maintenance.

Its integrated test sockets provide direct access for compatible measurement equipment without disturbing the wiring. Together with the sealable open position and distinctive grey and red construction, the 1SNA105142R2000 is particularly suitable for control, instrumentation and measurement circuits where clear identification and regular testing are important.

Typical Applications

• Industrial control panels and switchgear.
• Measurement and instrumentation circuits.
• PLC and automation system wiring.
• Machine building and OEM electrical equipment.
• Commissioning and diagnostic test circuits.
• Control circuits requiring convenient maintenance isolation.
