The TE Connectivity DB2.5/5.2L 1SNA290241R1000 is a compact spring-clamp terminal block designed for reliable electrical connections in industrial control panels, machinery and automation systems. Part of the established Entrelec SNA terminal block range, it combines a space-saving miniblock design with dependable spring connection technology for efficient panel wiring.
The DB2.5/5.2L provides consistent conductor clamping without relying on operator-applied tightening torque. Its spring connection automatically maintains contact pressure, helping compensate for conductor movement and creep over time. Front wiring access and a compact angled design make the terminal particularly suitable for installations where panel space and accessibility are important.
With a rated cross-section of 2.5 mm², rated current of 24 A and rated voltage of 800 V, the 1SNA290241R1000 provides a robust connection solution for industrial circuits. Its compact 5 mm width, grey polyamide housing and IP20 terminal protection make it well suited to high-density control and distribution applications.
Spring-clamp terminal blocks maintain electrical contact by applying continuous spring pressure to the conductor. Unlike connections that depend on manually applied screw torque, the spring mechanism provides consistent clamping pressure and automatically compensates for conductor creep, helping maintain a secure electrical connection throughout the service life of the installation.
The Entrelec SNA range is designed for industrial control and distribution applications where reliable connections and efficient use of panel space are essential. The DB2.5/5.2L combines front conductor access, compact dimensions and a broad conductor capacity, making it a practical choice for machine builders, panel builders and industrial automation engineers.
