Why Choose the TE Connectivity D2.5/5.I.N.4L 1SNA399070R1500 Terminal Block?

The TE Connectivity D2.5/5.I.N.4L 1SNA399070R1500 is a compact blue spring-clamp feed-through terminal block with four connections designed for reliable conductor termination and distribution in industrial control panels, machinery and automation systems. Part of the established Entrelec SNA spring terminal block range, it combines high connection density with dependable spring connection technology and DIN rail mounting.

The D2.5/5.I.N.4L provides four clamping positions on a single level, allowing multiple conductors to be interconnected within a narrow 5 mm terminal width. Spring-clamp technology maintains consistent contact pressure without relying on screw-tightening torque, helping simplify installation and reduce routine maintenance requirements.

With a 2.5 mm² nominal cross-section, 24 A rated current and 800 V rated voltage, the D2.5/5.I.N.4L provides a space-efficient solution for industrial control and distribution wiring. Its blue insulating body also makes it particularly useful where colour-coded circuit identification is required within densely populated electrical panels.

Reliable Four-Connection Spring Terminal Technology

Spring-clamp terminal technology applies controlled pressure to the conductor without depending on installer tightening torque. This provides a dependable electrical connection and makes spring terminals well suited to industrial machinery, automation cabinets and other applications where vibration, repeated temperature changes and long-term connection reliability are important.

The four-connection design of the D2.5/5.I.N.4L enables several conductors to share the same electrical potential without occupying multiple individual terminal positions. Combined with its narrow 5 mm footprint, this makes the terminal particularly useful for high-density signal, control and distribution wiring.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Signal and control wiring.
• Multi-conductor distribution circuits.
• Process-control installations.
• High-density DIN rail terminal assemblies.
• Colour-coded electrical circuit identification.
