Why Choose the TE Connectivity D2.5/5.A.LLP.L 1SNA290340R2700 Terminal Block?

The TE Connectivity / ENTRELEC D2.5/5.A.LLP.L 1SNA290340R2700 is a compact three-level spring-clamp installation terminal block developed for high-density industrial wiring and TN-C-S network applications. Part of the ENTRELEC SNA spring terminal range, it combines multiple connection levels with a narrow 5 mm width to maximise available DIN rail space in control panels, machinery and distribution equipment.

The D2.5/5.A.LLP.L uses spring-clamp connection technology, providing consistent contact pressure that is not dependent on installer-applied screw torque. Automatic compensation for conductor settling helps maintain dependable electrical connections over time, while front wiring entry makes the terminal easier to access during installation, testing and maintenance.

Rated at 24 A and 250 V for the main circuit, the terminal accepts rigid conductors from 0.14–4 mm² and flexible conductors from 0.14–2.5 mm². Its grey polyamide housing, IP20 terminal protection, UL 94 V-0 flammability classification and operating range of -55 to +110 °C make it suitable for demanding industrial electrical installations.

Key Advantages

• Three-level installation terminal maximises wiring density within a compact footprint.
• Specially developed for TN-C-S network applications.

High-Density Spring-Clamp Wiring for Industrial Panels

The D2.5/5.A.LLP.L is designed to accommodate multiple electrical connections within a compact DIN rail footprint. Its three-level construction and 5 mm width make it particularly valuable in applications where enclosure space is limited and a high density of field wiring must be organised without compromising accessibility.

Spring-clamp technology applies continuous pressure to the conductor and automatically compensates for conductor settling, helping maintain a reliable electrical connection without routine screw retightening. Combined with front wiring entry and compatibility with standard TH35-7.5 and TH35-15 DIN rails, the terminal provides a practical solution for industrial distribution, machinery and automation wiring.

Typical Applications

• TN-C-S electrical network installations.
• Industrial electrical control panels.
• High-density multi-level terminal assemblies.
• PLC and automation cabinets.
• Machinery wiring and control systems.
• Switchboards and electrical distribution equipment.
• Process control and instrumentation panels.
• OEM machine and panel building.
