1sna399068r1700 – d2.5/5.1.3l

Why Choose the TE Connectivity D2.5/5.I.3L 1SNA399068R1700 Terminal Block?

The TE Connectivity D2.5/5.I.3L 1SNA399068R1700 is a compact spring-clamp feed-through terminal block with three 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 space-efficient DIN rail mounting with dependable spring connection technology.

The D2.5/5.I.3L uses front-entry spring connections that simplify conductor access while maintaining clamping pressure independently of the installer. Automatic compensation for conductor creep helps maintain a secure electrical connection without routine retightening, making the terminal particularly suitable for demanding industrial installations.

With a 2.5 mm² rated cross-section, 24 A rated current and 800 V rated voltage, this grey feed-through terminal provides three connection points in a compact 5 mm pitch. Integrated provisions for jumpering, marking and testing further simplify installation and maintenance within densely populated control cabinets.

Key Advantages

• Compact three-connection feed-through terminal block for industrial wiring.
• Spring-clamp technology provides consistent contact pressure without routine retightening.
• Front conductor entry provides convenient access during panel wiring.
• 24 A rated current and 800 V rated voltage for demanding control applications.
• Only 5 mm wide, helping maximise available DIN rail space.
• Integrated double jumper system, marking provision and test sockets support efficient panel assembly.

Reliable Spring-Clamp Connections for Industrial Wiring

Spring-clamp terminal technology maintains controlled contact pressure on the conductor independently of operator tightening torque. This provides a reliable electrical connection while eliminating the routine retightening associated with conventional screw connections and helps the terminal withstand vibration and changing operating conditions.

The D2.5/5.I.3L also incorporates practical panel-building features including front wiring entry, a double jumper system, clearly visible marker positioning and test sockets. Its narrow 5 mm footprint makes it especially useful where a high number of connections must be accommodated within limited DIN rail space.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Signal and control wiring.
• Power and control distribution circuits.
• Process-control installations.
• High-density DIN rail terminal assemblies.
