Why Choose the TE Connectivity D2,5/5.A.NTLP.L.V0 1SNA290336R0700 Terminal Block?

The TE Connectivity D2,5/5.A.NTLP.L.V0 1SNA290336R0700 is a compact multi-level spring-clamp installation terminal block designed for efficient neutral, line and protective conductor distribution in industrial electrical panels. Part of the established Entrelec SNA spring terminal block range, it is specifically developed for TN-C-S network applications where space-saving wiring, reliable conductor termination and convenient neutral isolation are required.

The D2,5/5.A.NTLP.L.V0 uses spring-clamp connection technology to provide consistent contact pressure independently of the installer while automatically compensating for conductor creep. Its front wiring entry improves accessibility during installation and maintenance, while the compact angled terminal design enables several circuit functions to be accommodated within a narrow 5 mm pitch.

With a 2.5 mm² rated cross-section, 20 A rated current and 250 V rated voltage, this installation terminal provides a practical solution for industrial control and distribution assemblies. The integrated neutral-disconnection functionality supports convenient circuit isolation, while standard TH35 DIN rail mounting simplifies integration into control cabinets and switchgear.

Reliable Spring-Clamp Distribution for Industrial Panels

Spring-clamp terminal technology maintains conductor contact using resilient spring pressure rather than relying on a conventional screw connection. This provides repeatable contact pressure independent of installation torque and automatically compensates for conductor movement and material creep, supporting reliable electrical connections throughout the service life of the panel.

The D2,5/5.A.NTLP.L.V0 combines this connection technology with a compact multi-level layout specifically suited to TN-C-S distribution. Its front-entry design improves conductor accessibility, while the neutral-disconnection facility makes isolation and testing more convenient during commissioning and maintenance.

Typical Applications

• TN-C-S electrical distribution networks.
• Industrial control and automation panels.
• Neutral, line and protective conductor distribution.
• Electrical distribution cabinets and switchgear.
• Machine control and OEM electrical systems.
• High-density DIN rail wiring assemblies.
