1sna290231r0600 – ds2.5/10

Why Choose the TE Connectivity DS2.5/10.4L 1SNA290231R0600 Terminal Block?

The TE Connectivity / ENTRELEC DS2.5/10.4L 1SNA290231R0600 is a compact 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 compact dimensions with front-entry wiring and maintenance-free spring-clamp technology.

The DS2.5/10.4L provides four connection points on a single level, allowing 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 grey housing measures just 10 mm wide and mounts directly onto standard TH35 DIN rail, making it suitable for compact, high-density panel layouts.

Key Advantages

• Four spring-clamp connections in a compact single-level terminal.
• Rated for up to 24 A at 800 V to IEC specifications.
• Accommodates rigid conductors up to 4 mm².
• Front-entry wiring provides convenient conductor access during installation.
• Spring technology maintains consistent contact pressure without screw retightening.
• Compact 10 mm width helps optimise DIN rail space.
• Mounts on standard TH35-7.5 and TH35-15 DIN rails.

Key Features

• TE Connectivity / ENTRELEC SNA spring terminal series.
• DS2.5/10.4L four-connection Miniblock design.
• Spring-clamp connection technology.
• Four clamping positions on one level.
• Grey thermoplastic insulating housing.
• IP20 protection at the main terminals.
• Operating temperature range of -55 to +110 °C.
• Rated impulse withstand voltage of 8 kV.
• Compact DIN rail mounting format for industrial panel applications.

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 DS2.5/10.4L 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. Mounting onto standard TH35 DIN rail also simplifies integration with other terminal blocks and control components in modular industrial assemblies.

Typical Applications

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