1sna299509r1300 – db4/8,ado
TE Connectivity DB4/8.ADO 1SNA299509R1300 is a grey 8 mm pitch feed-through mini terminal block with ADO and screw-clamp connections, rated at 24 A and 800 V for compact industrial control and automation wiring.
Why Choose the TE Connectivity DB4/8.ADO 1SNA299509R1300 Terminal Block?
The TE Connectivity DB4/8.ADO 1SNA299509R1300 is a compact feed-through mini terminal block designed for reliable electrical connections in industrial control panels, machinery and automation systems. Part of the established Entrelec ADO System, it combines automatic direct opening connection technology with a standard screw-clamp connection, making it well suited to applications where installation space is restricted.
The DB4/8.ADO features an 8 mm spacing, a nominal cross-section of 2.5 mm² and an IEC rated current of 24 A. The ADO connection accepts rigid and flexible conductors from 1–2.5 mm², while the screw-clamp connection accommodates rigid conductors from 0.2–4 mm² and flexible conductors from 0.22–4 mm².
With an IEC rated voltage of 800 V, an impulse withstand voltage of 8,000 V and IP20 protection, the grey polyamide terminal block provides a compact solution for demanding industrial wiring. Its flange-based mounting arrangement enables straightforward installation in compatible terminal block assemblies.
