1sna290233r0000 – ds2.5/10.n.4l

Why Choose the TE Connectivity DS2.5/10.N.4L 1SNA290233R0000 Terminal Block?

The TE Connectivity / ENTRELEC DS2.5/10.N.4L 1SNA290233R0000 is a compact blue four-connection spring-clamp feed-through terminal block designed for reliable conductor connection in industrial control panels, machinery and automation equipment. Part of the ENTRELEC SNA spring terminal range, it combines a space-saving Miniblock design with front-entry wiring and maintenance-friendly spring-clamp technology.

The DS2.5/10.N.4L provides four connection points on a single level, allowing multiple conductors to be interconnected through one compact terminal. Its spring-clamp connection system maintains consistent contact pressure independently of the installer and automatically compensates for conductor settling, helping provide dependable electrical performance throughout the installation's service life.

Rated at 24 A and 800 V to IEC specifications, the terminal accepts rigid conductors from 0.12–4 mm² and flexible conductors from 0.12–2.5 mm². The blue housing provides clear identification within terminal assemblies, while the compact 10 mm width and TH35 DIN rail mounting make it suitable for high-density industrial panel layouts.

Reliable Spring-Clamp Connections for Industrial Panels

Spring-clamp terminal technology provides a reliable alternative to conventional screw connections by applying continuous pressure to the connected conductor. This helps compensate automatically for conductor settling and removes the need for routine screw retightening, making the DS2.5/10.N.4L particularly suitable for machinery and automation installations where dependable long-term connections are important.

The combination of four connection points, front-entry wiring and a 10 mm footprint allows several conductors to be interconnected efficiently without unnecessarily increasing panel space. Its blue housing also makes it useful where colour-coded identification is required, while mounting on standard TH35-7.5 and TH35-15 rails simplifies integration into modular industrial terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machinery wiring and control systems.
• Multi-conductor feed-through connections.
• Colour-coded terminal assemblies.
• Switchboards and electrical distribution equipment.
• Process control and instrumentation panels.
• OEM machine and panel building.
