The TE Connectivity DR2.5/8.P.ADO 1SNA299633R0600 is a compact green/yellow protective-earth terminal block with ADO insulation displacement connections. Part of the established TE Connectivity / Entrelec SNA ADO range, this miniblock is designed for dependable protective-earth connections in industrial control panels, machinery and automation equipment where installation space is restricted.
The DR2.5/8.P.ADO uses ADO connection technology on both conductor connections, providing fast and consistent conductor termination while supporting up to two wires per connection. Its screwless rail contact establishes the protective-earth connection to the mounting rail without relying on an operator-adjusted rail-contact screw, helping provide secure grounding in demanding industrial installations.
With a rated cross-section of 2.5 mm², conductor capacity from 1–2.5 mm² and a rated short-time withstand current of 300 A for 1 s, the 1SNA299633R0600 provides robust protective-earth connectivity in a compact 8 mm-wide format. Its green/yellow housing provides immediate protective-earth identification, while IP20 protection supports safe integration into enclosed electrical equipment.
Protective-earth terminal blocks provide the essential connection between equipment protective conductors and the grounding system of an electrical installation. The DR2.5/8.P.ADO combines this function with the Entrelec ADO System, using insulation displacement technology to provide reliable conductor connections without conventional conductor-clamping screws.
The terminal's screwless rail contact provides the protective-earth connection directly to its compatible mounting rail and avoids dependence on operator-applied rail-contact torque. Together with its compact 8 mm profile and support for up to two wires per connection, this makes the DR2.5/8.P.ADO particularly useful for densely populated industrial control and automation panels.
