1sna400219r1100 – d2,5/5,i,3l jaune

Why Choose the TE Connectivity D2.5/5.I.3L 1SNA400219R1100 Spring Terminal Block?

The TE Connectivity D2.5/5.I.3L 1SNA400219R1100 is a yellow spring-clamp feed-through terminal block with three connections from the Entrelec SNA Spring range. Designed for compact industrial wiring, it provides three conductor connection points within a slim 5 mm terminal profile.

Rated at 24 A and 800 V IEC with a nominal conductor cross-section of 2.5 mm², the D2.5/5.I.3L supports rigid conductors from 0.12 to 4 mm² and flexible conductors from 0.12 to 2.5 mm². Spring-clamp technology provides consistent conductor contact without the routine tightening associated with screw-clamp connections.

The terminal mounts on standard TH35-7.5 and TH35-15 DIN rails and features IP20 finger protection, a V0 thermoplastic insulating body and an operating temperature range of -55 to +110 °C. Its three-connection design is particularly useful where an incoming circuit needs an additional connection point while preserving a compact terminal-strip footprint.

Key Advantages

• Three spring-clamp connections provide flexible wiring within one compact terminal.
• Rated at 24 A / 800 V IEC for industrial control and distribution circuits.
• Compact 5 mm width helps maximise available DIN-rail space.

Compact Three-Connection Spring-Clamp Technology

Spring-clamp terminal technology maintains conductor contact through spring force rather than a tightened screw, providing a reliable connection that does not depend on maintaining screw torque. The D2.5/5.I.3L accommodates rigid conductors up to 4 mm² and flexible conductors up to 2.5 mm², making it suitable for a broad range of control and automation wiring.

Its three connection positions provide additional wiring flexibility compared with a conventional two-connection feed-through terminal. Combined with a width of only 5 mm, this allows engineers to create high-density terminal assemblies while retaining an additional connection point for branching or distribution within the same electrical potential.

Typical Applications

• Industrial control-panel wiring.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Signal and control circuit distribution.
• Instrumentation wiring.
• High-density DIN-rail terminal assemblies.
• Circuits requiring three connection points at a common potential.
