Why Choose the TE Connectivity D2.5/5.ADO Orange Terminal Block?
The TE Connectivity D2.5/5.ADO, part number 1SNA199555R2400, is an orange feed-through DIN rail terminal block designed for reliable conductor connection in industrial control panels, electrical distribution equipment and automation systems. Part of the established Entrelec SNA ADO terminal block range, it combines an ADO connection with a conventional screw-clamp connection in a compact 5 mm-wide housing.
The D2.5/5.ADO provides the flexibility of the ADO connection system while retaining a standard screw-clamp interface for straightforward field wiring. Its single-level feed-through configuration is suitable for organised point-to-point connections, while the compact 5 mm spacing helps maximise wiring density inside control cabinets and machinery.
With an IEC rated current of 13.5 A, rated voltage of 1000 V and IP20 terminal protection, this terminal block is engineered for dependable industrial wiring. It mounts on standard TH35-7.5 and TH35-15 DIN rails and features an orange polyamide insulating body for clear circuit identification.
