Why Choose the TE Connectivity DR4/8.ADO Grey Miniblock 1SNA199279R1700?
The TE Connectivity 1SNA199279R1700, type DR4/8.ADO, is a compact grey feed-through DIN rail terminal miniblock from the ENTRELEC SNA ADO range, designed for reliable conductor connections where panel space is restricted. Combining ADO System connection technology with a conventional screw-clamp connection, it provides a practical interface for industrial control, distribution and automation wiring.
The DR4/8.ADO is specifically designed as a miniblock for installations with demanding space constraints. Its 8 mm spacing and compact body allow dense terminal arrangements, while the combined ADO and screw-clamp connection concept provides flexibility when terminating field and control wiring.
With a 24 A rated current, 1000 V rated voltage and conductor capability suited to typical control-panel wiring, the 1SNA199279R1700 provides a robust solution for feed-through connections. The terminal mounts on TH15-5.5 DIN rail and has compact dimensions of approximately 31 × 8 × 18.5 mm (H × W × D).
