1sna146281r2400 – d4/6,ado,ex
TE Connectivity D4/6.ADO.Ex 1SNA146281R2400 is a light-grey 1.5 mm² SNA series feed-through terminal block with screw-clamp and ADO System connection technology for industrial DIN rail and appropriately engineered Ex installations.
Why Choose the TE Connectivity D4/6.ADO.Ex 1SNA146281R2400 Terminal Block?
The TE Connectivity D4/6.ADO.Ex 1SNA146281R2400 is a compact light-grey feed-through terminal block from the Entrelec SNA range, engineered for industrial control, automation and process wiring. It combines traditional screw-clamp termination with Entrelec's ADO System, providing a versatile connection solution within a narrow DIN rail footprint.
Designed with a 1.5 mm² rated cross-section and only 6 mm spacing, the D4/6.ADO.Ex enables high-density terminal assemblies without sacrificing accessibility. Its single-level feed-through configuration provides a straightforward electrical path, while durable polyamide insulation supports dependable service in demanding industrial environments.
The terminal measures approximately 45 × 6 × 41 mm and mounts on standard TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715. The D4/6.ADO.Ex is also covered by the LCIE 02 ATEX 0020 U component certification family, supporting integration into appropriately designed and certified equipment for potentially explosive atmospheres.
