The TE Connectivity / Entrelec DS2.5/5.2L 1SNA290221R0400 is a compact grey spring-clamp feed-through terminal block from the SNA Miniblocks range, designed for reliable conductor connection in industrial control panels and automation equipment. Its single-level design provides two connection points with a compact 5 mm pitch.
The DS2.5/5.2L uses spring-clamp technology to provide consistent contact pressure independently of operator tightening. Front conductor entry improves accessibility during wiring, while the compact angled housing helps save valuable DIN-rail space in densely populated electrical panels.
Rated at 24 A and 800 V under IEC specifications, the terminal block has a rated cross-section of 2.5 mm² and accepts rigid conductors from 0.12–4 mm². It mounts on standard TH35 DIN rail, features IP20 protection at the main terminals and uses V0-rated thermoplastic insulation.
The DS2.5/5.2L combines a compact angled housing with spring-clamp conductor termination, making it particularly suitable for control panels where installation space and wiring accessibility are important. Spring contact pressure is maintained independently of the installer, with automatic compensation helping preserve a dependable electrical connection over time.
Mounting on standard TH35 DIN rail allows straightforward integration into conventional industrial terminal assemblies. With a 5 mm pitch, two feed-through connections and front conductor entry, the 1SNA290221R0400 provides a practical solution for signal, control and power wiring within its specified electrical ratings.
