Why Choose the TE Connectivity 1SNA115314R1500 M4/6.ST.Au Disconnect Terminal Block?
The TE Connectivity 1SNA115314R1500, also identified as the ENTRELEC M4/6.ST.Au, is a compact screw-clamp test disconnect terminal block with gold contact blades designed for signal, test and measurement circuits in industrial control panels and automation systems. As part of the established ENTRELEC SNA terminal block series, it combines reliable screw termination with a plug-operated disconnect function for convenient circuit testing and isolation.
The M4/6.ST.Au is the gold-contact version of the M4/6.ST test disconnect terminal family. Its gold contact base material provides a dependable contact interface for instrumentation and signal applications, while compatible disconnect plugs allow circuits to be tested or isolated without removing the permanently connected conductors.
With an IEC rated current of 5 A, an IEC rated voltage of 500 V and conductor capacity from 0.5–4 mm², the 1SNA115314R1500 is well suited to industrial test and measurement wiring. Its compact 6 mm width and compatibility with G32, TH35-7.5 and TH35-15 DIN rails allow efficient installation in densely populated control and instrumentation cabinets.
