Why Choose the TE Connectivity D2,5/5.I.N.3L 1SNA399067R0600 Spring Terminal Block?

The TE Connectivity D2,5/5.I.N.3L 1SNA399067R0600 is a compact three-connection feed-through spring terminal block designed for dependable conductor connection in industrial control panels, machinery and electrical distribution systems. Part of the established Entrelec SNA spring terminal block range, it combines space-efficient DIN-rail installation with fast spring-clamp termination.

This blue feed-through terminal provides three connection positions on a single level and has a nominal conductor cross-section of 2.5 mm². Its spring connection technology supports secure, vibration-resistant conductor termination without relying on conventional screw tightening, making it particularly useful for industrial installations requiring efficient assembly and consistent connection quality.

With a narrow 5 mm width, the D2,5/5.I.N.3L helps maximise available DIN-rail space while supporting rigid conductors from 0.12–4 mm². It is rated at 24 A and 800 V under IEC specifications and provides IP20 protection at the main terminals for use inside suitable electrical enclosures.
