TE Connectivity DB2.5/10.N.4L 1SNA290253R1400 is a blue spring-clamp feed-through Miniblock terminal with a 2.5 mm² nominal conductor size, 24 A rated current and 800 V rated voltage for industrial electrical installations.
Why Choose the TE Connectivity DB2.5/10.N.4L 1SNA290253R1400 Spring Terminal Block?
The TE Connectivity / Entrelec DB2.5/10.N.4L 1SNA290253R1400 is a compact blue spring-clamp feed-through terminal block from the SNA Spring range, designed for reliable conductor connection in industrial control panels, automation equipment and electrical distribution systems. Its Miniblock construction combines a compact footprint with convenient front-entry wiring for efficient panel assembly.
Spring-clamp connection technology maintains controlled contact pressure without relying on installer-applied screw torque, helping provide consistent electrical connections while compensating for conductor settling over time. The DB2.5/10.N.4L provides a practical solution for applications where dependable connections and space-efficient wiring are important.
The 1SNA290253R1400 has a rated current of 24 A and rated voltage of 800 V. It accepts flexible conductors from 0.12–2.5 mm² and rigid conductors from 0.12–4 mm², while its distinctive blue insulating body makes it particularly suitable for neutral conductor identification within organised electrical assemblies.
Front-entry wiring provides convenient conductor access during installation and servicing.
Accepts both flexible and rigid conductors for versatile industrial wiring.
24 A / 800 V electrical ratings support a broad range of control and distribution applications.
