Why Choose the TE Connectivity D2.5/8.ADO Orange Feed-Through Terminal Block?
The TE Connectivity 1SNA199060R0300 D2.5/8.ADO is a compact orange ADO feed-through terminal block designed for reliable conductor connections in industrial control panels, machinery and automation systems. Part of the established ENTRELEC SNA ADO range, it uses ADO insulation displacement connection technology on both sides for fast, secure and vibration-resistant industrial wiring.
The D2.5/8.ADO has a rated cross-section of 2.5 mm², a rated current of 24 A and a rated voltage of 1000 V. Its 8 mm pitch provides an efficient modular format, while the orange housing makes the terminal easy to distinguish from other circuits within a populated terminal strip.
Designed for installation on TH35-7.5 and TH35-15 DIN rails, this terminal block accepts 1–2.5 mm² rigid or flexible conductors and provides IP20 protection at the main terminals. Its thermoplastic insulation, UL 94 V-0 flammability classification and operating temperature range of -55 to +110 °C support dependable use in demanding industrial environments.
