The TE Connectivity DB2.5/5.N.2L 1SNA290243R1200 is a compact blue spring-clamp feed-through terminal block designed for reliable conductor connections in industrial control panels, machinery and automation systems. As part of the established TE Connectivity / Entrelec SNA terminal block series, it combines a space-saving miniblock format with spring connection technology for efficient and dependable panel wiring.
The DB2.5/5.N.2L uses a spring-clamp connection that maintains consistent contact pressure independently of operator-applied tightening torque while automatically compensating for conductor creep. Its compact angled construction and front wiring entry provide convenient conductor access, making it particularly useful in high-density control cabinets where installation space is limited.
With a rated cross-section of 2.5 mm², rated current of 24 A and rated voltage of 800 V, the 1SNA290243R1200 provides a robust connection solution for industrial electrical circuits. Its distinctive blue housing makes it suitable for neutral conductor identification, while the compact 5 mm width helps maximise available panel space.
Spring-clamp terminal blocks maintain electrical contact by applying continuous spring pressure to the conductor. This provides consistent clamping pressure independently of operator-applied tightening torque and automatically compensates for conductor creep, helping maintain a secure electrical connection throughout the service life of the installation.
The SNA miniblock range is designed for industrial control and distribution applications where reliable connections and efficient use of panel space are essential. The DB2.5/5.N.2L combines front conductor access, compact dimensions and broad conductor compatibility with a blue housing that enables straightforward identification within organised electrical wiring systems.
