Why Choose the TE Connectivity 1SNA199098R2600 D1.5/6.P.ADO Earth Terminal Block?
The TE Connectivity 1SNA199098R2600, also known as the D1.5/6.P.ADO or ADO/ADO D1.5/6.P.EARTH, is a compact 1.5 mm² protective earth DIN rail terminal block from the Entrelec SNA ADO range. Designed for reliable grounding in industrial control panels, machinery and electrical enclosures, it combines ADO insulation displacement connections with a screwless rail contact for efficient and dependable protective earth wiring.
The ADO System uses screwless insulation displacement connection technology to provide consistent conductor termination while reducing installation time. The D1.5/6.P.ADO also features a non-operator-dependent screwless rail contact, helping establish a secure protective earth connection to the DIN rail while simplifying mounting and removal during panel assembly and maintenance.
With a rated cross-section of 1.5 mm², a conductor capacity of 0.34–1.5 mm² and a short-time withstand current of 180 A for 1 s, the 1SNA199098R2600 is designed for dependable protective earth connections. Its compact 6 mm width, green/yellow identification and compatibility with standard TH35 DIN rails make it ideal for high-density industrial control cabinets.

Reliable Protective Earth Connections for Industrial Panels
Protective earth terminal blocks provide an essential connection between equipment conductors and the grounded DIN rail within an electrical installation. The D1.5/6.P.ADO combines this grounding function with the Entrelec ADO System, allowing conductors to be terminated using screwless insulation displacement technology while its dedicated rail contact provides the protective earth path.
The compact design is particularly useful in densely populated control cabinets where reliable grounding must be achieved without consuming unnecessary DIN rail space. Its green/yellow body provides clear protective earth identification, while the ability to accommodate up to two wires per connection gives panel builders additional flexibility when organising grounding circuits.
Typical Applications
- Protective earth connections in industrial control panels.
- Machine building and OEM automation systems.
- PLC and process control cabinets.
- Electrical switchgear and distribution assemblies.
- Factory automation equipment.
- Building automation and control systems.
- High-density DIN rail grounding assemblies.
