The TE Connectivity 1SNA199447R2000 M4/6.D2.2S2.T23 is a compact double-deck disconnect terminal block with integrated test sockets, designed for measurement, control and industrial automation circuits. Part of the established ENTRELEC SNA screw-clamp range, it provides two independently disconnectable circuits within a terminal only 6 mm wide, helping maximise wiring density in crowded control panels.
Each deck has its own disconnect mechanism, with a black pull lever controlling the upper contact and a grey pull lever controlling the lower contact. In addition, the T23 configuration incorporates two built-in test sockets, providing convenient access for compatible test equipment during commissioning, measurement, troubleshooting and maintenance.
The M4/6.D2.2S2.T23 has a rated cross-section of 4 mm², a rated current of 10 A and a rated voltage of 500 V. Its screw-clamp connections accommodate flexible conductors from 0.2–4 mm², while IP20 main-terminal protection, a -55 to +110 °C operating range and TH35/G32 rail compatibility make it suitable for demanding industrial installations.
The M4/6.D2.2S2.T23 combines two independently controlled circuits within a single 6 mm-wide terminal, reducing the DIN rail space required compared with installing separate disconnect terminals. Dedicated black and grey pull levers provide clear visual identification and allow either circuit to be isolated independently during commissioning, servicing or troubleshooting.
The T23 configuration adds two built-in test sockets, providing convenient access to both circuits for compatible measuring and test equipment. This combination of independent isolation and integrated test access makes the terminal particularly useful in instrumentation, process control and automation applications where regular circuit testing must be performed efficiently.
