Why Choose the TE Connectivity 1SNA115529R1500 M6/8.STP1 Push-Turn Disconnect Terminal Block?
The TE Connectivity 1SNA115529R1500 M6/8.STP1 is a robust screw-clamp disconnect terminal block from the ENTRELEC SNA series, designed for reliable signal circuit connection, isolation and testing in industrial control panels and automation systems. Its quarter-turn push-turn disconnect knob allows circuits to be conveniently opened and closed without removing the connected conductors.
The M6/8.STP1 incorporates two integrated 4 mm test sockets, providing convenient access for electrical measurement and diagnostic work. The push-turn knob can also be sealed in both the open and closed positions, helping support controlled circuit isolation during commissioning, maintenance and fault-finding operations.
With a 500 V IEC voltage rating, 15 A IEC current rating and 6 mm² nominal conductor size, the 1SNA115529R1500 is suited to industrial signal and control wiring. Its compact 8 mm spacing and compatibility with G32, TH35-7.5 and TH35-15 DIN rails make it straightforward to integrate into modular electrical panel assemblies.
