Why Choose the TE Connectivity D2.5/5.A.NLP.L 1SNA290338R1100 Terminal Block?

The TE Connectivity / ENTRELEC D2.5/5.A.NLP.L 1SNA290338R1100 is a compact three-level spring-clamp installation terminal block developed for efficient wiring in industrial control panels and TN-C-S electrical networks. Part of the ENTRELEC SNA spring terminal range, it combines multiple connection levels with a narrow 5 mm spacing to maximise wiring density on the DIN rail.

The D2.5/5.A.NLP.L uses spring-clamp connection technology, providing consistent conductor contact pressure independently of the installer and automatically compensating for conductor settling. Front wiring entry improves accessibility during installation and maintenance, while the angled terminal design helps save valuable space inside densely populated electrical enclosures.

Rated at 24 A and 250 V for the main circuit, the terminal accommodates rigid conductors from 0.14–4 mm² and flexible conductors from 0.14–2.5 mm². Its grey polyamide housing, IP20 terminal protection and wide -55 to +110 °C operating temperature range make it well suited to demanding industrial panel-building applications.

High-Density Spring-Clamp Wiring for Industrial Panels

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

Spring-clamp technology applies continuous pressure to the conductor, 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 installation, 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.
