1sna399319r1700 – d4/8.n.ado.3 terminal block [pk=50]

Why Choose the TE Connectivity D6/8.N.ADO3 1SNA399319R1700 Terminal Block?

The TE Connectivity D6/8.N.ADO3 1SNA399319R1700 is a blue ADO System feed-through DIN rail terminal block with an ADO connection and screw-clamp connection, designed for dependable neutral conductor termination in industrial control panels, machinery and automation systems. Part of the established Entrelec SNA terminal block range, it combines rapid ADO wiring technology with the flexibility of a conventional screw connection.

The D6/8.N.ADO3 provides the benefits of the ADO insulation displacement connection system, which enables fast conductor termination, while its screw-clamp side accommodates conventional wiring practices. This hybrid connection arrangement makes the terminal particularly useful where efficient panel assembly and flexible field wiring are both required.

Designed for conductors up to 4 mm², the D6/8.N.ADO3 has an IEC rated current of 32 A and rated voltage of 1000 V. Its blue housing identifies it for neutral circuit applications, while the compact 8 mm spacing and standard TH35 DIN rail mounting support efficient installation in industrial electrical cabinets.
