1SNA199527R1000 – DS4/8,P,ADO

Why Choose the TE Connectivity DS4/8.P.ADO 1SNA199527R1000 Ground Terminal Block?

The TE Connectivity DS4/8.P.ADO 1SNA199527R1000 is a compact green-yellow protective earth miniblock from the ENTRELEC SNA ADO range. Designed for applications where panel space is restricted, it combines an ADO insulation displacement connection with a conventional screw-clamp connection and provides a direct protective earth connection to the DIN rail.

The DS4/8.P.ADO has a rated cross-section of 2.5 mm² and an 8 mm spacing. Its screw-clamp side accepts rigid conductors from 0.2–4 mm², while the ADO connection provides the benefits of insulation displacement termination and can accommodate up to two wires per connection.

Measuring approximately 49 × 8 × 28 mm (H × W × D), the 1SNA199527R1000 provides a compact protective earth solution for TH35-7.5 and TH35-15 DIN rails. A screwless rail-contact system provides the earth connection to the mounting rail, while the green-yellow polyamide housing ensures immediate visual identification as a protective conductor terminal.

Key Advantages

• Dedicated protective earth miniblock for industrial DIN rail installations.
• Combines ADO insulation displacement and screw-clamp connection technologies.

Reliable Protective Earth Connections in Compact Panels

Protective earth terminals provide a dependable connection between equipment protective conductors and the grounded mounting rail. The DS4/8.P.ADO uses a screwless rail contact designed to provide the protective earth connection independently of operator tightening, helping create consistent grounding arrangements within industrial terminal strips.

The combination of ADO technology and a conventional screw clamp gives installers flexibility when terminating conductors, while the compact 8 mm profile makes the terminal particularly suitable for densely populated panels. Its 300 A for 1 s short-time withstand capability further supports its role in protective conductor installations.

Typical Applications

• Protective earth wiring in industrial control panels.
• PLC and factory automation cabinets.
• Machine and equipment grounding circuits.
• Process control and instrumentation systems.
• Compact DIN rail terminal assemblies.
• Industrial installations requiring green-yellow protective conductor terminals.
