1sna399600r2600 – d6/8.d2.ado doubledeck

Why Choose the TE Connectivity D6/8.D2.ADO Double-Deck Terminal Block?

The TE Connectivity / ENTRELEC D6/8.D2.ADO, manufacturer part number 1SNA399600R2600, is a compact double-deck feed-through DIN rail terminal block designed for high-density industrial wiring applications. Combining ADO insulation displacement connection technology with a conventional screw-clamp connection, it provides a flexible wiring solution for control panels, machinery and automation systems where dependable connections and efficient use of DIN rail space are essential.

The D6/8.D2.ADO provides two connection levels within a single 8 mm-wide terminal block, allowing more circuits to be accommodated without increasing the length of the terminal strip. The ADO System enables rapid conductor termination while the screw-clamp connection accommodates conventional wiring practices, making the terminal particularly useful for machine builders, panel builders and industrial maintenance applications.

With a rated current of 24 A, rated voltage of 800 V and rated impulse withstand voltage of 8,000 V, the 1SNA399600R2600 provides robust electrical performance for industrial control circuits. Its grey polyamide housing, IP20 protection and compatibility with standard TH 35 DIN rail make it well suited to professional electrical panel installations.
