1sna290330r1500 – d2,5/5,nl,l
TE Connectivity D2,5/5.NL.L 1SNA290330R1500 is a two-level 2.5 mm² spring-clamp installation terminal block rated at 24 A and 400 V for neutral and feed-through circuits in industrial electrical panels.
Why Choose the TE Connectivity D2,5/5.NL.L 1SNA290330R1500 Terminal Block?
The TE Connectivity D2,5/5.NL.L 1SNA290330R1500 is a compact two-level spring-clamp installation terminal block designed for neutral and feed-through circuits in industrial electrical panels. Originating from the Entrelec terminal block range, this grey and blue terminal is specifically designed for efficient wiring in TN-C-S networks and other control and distribution applications where reliable connections and space efficiency are important.
The D2,5/5.NL.L uses spring-clamp connection technology to provide consistent contact pressure independently of the installer, while automatic compensation helps maintain connection integrity over time. Front wiring entry makes conductors easy to access during panel assembly and maintenance, while the compact angled construction allows two connection levels to be accommodated within a narrow 5 mm pitch.
With a 2.5 mm² rated cross-section, 24 A rated current and 400 V rated voltage, the D2,5/5.NL.L is suitable for demanding industrial wiring applications. It mounts onto standard TH35 DIN rail and accepts both rigid and flexible copper conductors, providing a practical solution for high-density control cabinets and distribution assemblies.

Reliable Spring-Clamp Connections for Industrial Wiring
Spring terminal blocks maintain conductor contact using a resilient clamping mechanism rather than relying on a conventional screw connection. This provides repeatable contact pressure and helps compensate for conductor movement and material creep, supporting dependable electrical connections throughout the service life of a control or distribution panel.
The D2,5/5.NL.L combines this connection technology with a two-level angled design and front conductor entry. The result is a compact terminal solution that simplifies access while reducing the DIN rail length required for neutral and feed-through wiring circuits.
Typical Applications
- TN-C-S electrical distribution networks.
- Industrial control and automation panels.
- Neutral and feed-through conductor circuits.
- Electrical distribution cabinets.
- Machine control systems.
- High-density DIN rail wiring assemblies.
