The TE Connectivity M4/6.D2.SBT 1SNA115702R2300 is a compact double-deck screw clamp disconnect terminal block designed for signal wiring, testing and circuit isolation in industrial control panels and automation systems. Part of the proven TE Connectivity ENTRELEC SNA series, it combines two circuits within a single 6 mm footprint to help maximise DIN rail wiring density.
The M4/6.D2.SBT incorporates one disconnect circuit on the upper level and one independent feed-through circuit on the lower level. The upper circuit uses a polarised disconnect plug for convenient isolation, while four integrated 2 mm test sockets provide accessible measurement points for commissioning, diagnostics and maintenance.
With an IEC rating of 10 A at 250 V and a rated conductor cross-section of 4 mm², the 1SNA115702R2300 provides dependable performance for industrial signal circuits. Its screw-clamp connections accommodate rigid stranded and flexible conductors from 0.5–4 mm², while its polyamide 6.6 housing and IP20 protection support reliable use in industrial electrical enclosures.
Double-deck terminal blocks increase wiring density by arranging multiple circuits vertically within a single DIN rail footprint. The TE Connectivity M4/6.D2.SBT combines a disconnect circuit on the upper level with an independent feed-through circuit below, providing two useful wiring functions within only 6 mm of rail space.
The polarised plug disconnect allows the upper circuit to be isolated during commissioning, testing and maintenance without disturbing the connected conductors. Four integrated test sockets provide convenient measurement access, while screw-clamp termination helps maintain secure electrical connections in industrial machinery and automation equipment.
