1sna199053r2000 – d1.5/6 n.ad0.

Why Choose the TE Connectivity D1.5/6.N.ADO Feed-Through Terminal Block?

The TE Connectivity D1.5/6.N.ADO (1SNA199053R2000) is a compact blue neutral feed-through terminal block designed for reliable conductor connections in industrial control, automation and electrical distribution systems. Part of the established TE Connectivity ENTRELEC SNA ADO range, it uses the ADO insulation-displacement connection system to provide fast, secure wiring without conventional conductor stripping.

Designed for 1.5 mm² circuits, the D1.5/6.N.ADO accepts solid, stranded and flexible conductors from 0.34–1.5 mm². The ADO connection technology is particularly suited to demanding control applications exposed to vibration, shock and corrosive industrial environments, while allowing up to two conductors per connection point.

With a rated voltage of 1000 V, rated current of 17.5 A and compact 6 mm spacing, the 1SNA199053R2000 delivers high connection density without compromising electrical performance. Its blue polyamide housing identifies it for neutral-circuit applications, while compatibility with TH35 DIN rails enables straightforward integration into industrial terminal assemblies.

Reliable ADO Connections for Industrial Neutral Circuits

ADO insulation-displacement technology creates the electrical connection directly through the conductor insulation, reducing wiring preparation compared with conventional stripped-wire termination methods. This makes ADO terminals particularly useful for repetitive industrial panel wiring where installation speed, consistent connection quality and resistance to demanding operating conditions are important.

The TE Connectivity D1.5/6.N.ADO combines this connection technology with a compact 6 mm DIN rail format and blue neutral identification. Its 17.5 A current rating, 1000 V voltage rating and wide operating temperature range make it a dependable solution for neutral and feed-through wiring in industrial automation and control systems.

Typical Applications

• Neutral conductor connections in industrial control panels.
• PLC and automation cabinets.
• Machine control and auxiliary circuits.
• Process control and instrumentation systems.
• Industrial equipment exposed to vibration and shock.
• Electrical distribution and switchgear assemblies.
• OEM machinery and high-density terminal strips.
