1sna290382r0600 – d1,5/4,4l

Why Choose the TE Connectivity D1,5/4.4L 1SNA290382R0600 Spring Terminal Block?

The TE Connectivity 1SNA290382R0600, type D1,5/4.4L, is a compact four-connection spring-clamp feed-through terminal block designed for reliable conductor termination in industrial control, automation and distribution systems. Part of the established TE Connectivity / ENTRELEC SNA spring terminal block range, this version features an orange housing for distinctive circuit identification.

The D1,5/4.4L combines four conductor connections within a narrow 4 mm terminal spacing, helping panel builders achieve high wiring density without sacrificing accessibility. Spring-clamp technology maintains consistent contact pressure without relying on installer-applied screw torque, providing a convenient and maintenance-efficient connection method.

Rated at 18 A and 800 V to IEC specifications, the terminal has a rated cross-section of 1.5 mm². It accepts rigid conductors from 0.12–2.5 mm² and flexible conductors from 0.12–1.5 mm², while its IP20 construction and TH 35 DIN rail mounting make it well suited to professional industrial panel assemblies.

Reliable Four-Connection Spring Termination for Industrial Panels

Spring-clamp terminal technology maintains conductor contact using a resilient spring mechanism rather than installer-controlled screw torque. This provides repeatable clamping pressure and helps compensate for conductor movement over time, supporting dependable electrical connections throughout the service life of industrial equipment.

With four connection points in a compact 4 mm format, the D1,5/4.4L provides an efficient solution for feed-through and common-potential wiring where several conductors need to be connected within limited DIN rail space. Its orange housing also enables easy visual separation of designated circuits from standard grey or blue terminal groups.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-building electrical systems.
• Instrumentation and signal wiring.
• High-density DIN rail terminal assemblies.
• Four-conductor feed-through and common-potential connections.
