Why Choose the TE Connectivity DR2,5/5.N.2L 1SNA290203R1300 Spring Terminal Block?
The TE Connectivity 1SNA290203R1300, also known as DR2,5/5.N.2L, is a compact blue spring-clamp feed-through terminal block designed for reliable conductor connection in industrial control panels, machinery and automation systems. Part of the established TE Connectivity / ENTRELEC SNA Miniblocks range, it combines a space-saving 5 mm width with front wiring access and dependable spring connection technology.
The spring-clamp design provides consistent contact pressure independent of the installer and automatically compensates for conductor creep over time. This makes the DR2,5/5.N.2L particularly suitable for applications where secure, maintenance-efficient electrical connections are required. Its angled, compact construction also helps maximise available space inside densely populated control cabinets.
Rated at 24 A and 800 V, the terminal accepts rigid conductors from 0.12–4 mm² and flexible conductors without ferrules from 0.12–2.5 mm². The blue housing is suitable for clearly identifiable circuit arrangements, while mounting on TH 15-5.5 DIN rail supports compact terminal assemblies.

Reliable Spring Connections for Industrial Control Panels
Spring-clamp terminal blocks maintain conductor contact using a resilient spring mechanism rather than relying on installer-applied screw torque. This provides repeatable clamping pressure and automatic compensation for conductor movement, helping maintain dependable electrical connections throughout the service life of industrial equipment.
The compact DR2,5/5.N.2L Miniblock combines this connection technology with front wiring access and a narrow 5 mm profile. It is therefore well suited to densely populated control panels, machine cabinets and automation assemblies where both wiring accessibility and efficient use of DIN rail space are important.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine-building electrical systems.
- Instrumentation and control wiring.
- Compact DIN rail terminal assemblies.
- Industrial power and signal distribution circuits.
