Why Choose the TE Connectivity 1SNA105141R2700 M6/8.STP Disconnect Terminal Block?
The TE Connectivity 1SNA105141R2700 M6/8.STP, also referenced as M 6/8 STPA1, is a professional screw-clamp disconnect terminal block with push-turn knob from the ENTRELEC SNA series. Designed for industrial control, measurement and automation circuits, it provides a convenient means of disconnecting an individual circuit without removing the connected conductors.
The M6/8.STP features a ¼-turn push-turn disconnect mechanism that simplifies circuit isolation during commissioning, testing and maintenance. The disconnect can be sealed in the open position, while integrated 4 mm test sockets provide convenient access for electrical measurements and diagnostic work.
Designed around a 6 mm² nominal conductor cross-section and compact 8 mm spacing, the 1SNA105141R2700 has an IEC rating of 15 A at 500 V. Its grey and black construction, screw-clamp connections and compatibility with G32, TH35-7.5 and TH35-15 DIN rails make it a robust solution for industrial electrical panels and machinery.

Convenient Circuit Isolation and Testing
Disconnect terminal blocks provide a practical way to isolate individual circuits while leaving field wiring securely terminated. The M6/8.STP uses a ¼-turn push-turn mechanism to make disconnect operations quick and straightforward, making it particularly useful in measurement, control and instrumentation circuits where regular testing may be required.
Integrated test sockets allow technicians to connect suitable measuring equipment without disturbing the conductor connections. Combined with the ability to seal the disconnect in its open position, this makes the 1SNA105141R2700 particularly useful for commissioning, fault finding and planned maintenance within industrial electrical systems.
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.
- Circuits requiring convenient isolation for maintenance.
