1sna290372r1300 – d1,5/4,2l

Why Choose the TE Connectivity D1,5/4.2L 1SNA290372R1300 Spring Terminal Block?

The TE Connectivity D1,5/4.2L 1SNA290372R1300 is a compact spring-clamp feed-through terminal block designed for reliable conductor connection in industrial control panels, machinery and electrical distribution systems. Part of the established Entrelec SNA spring terminal block range, this orange terminal provides two connections and combines high-density DIN rail installation with convenient front-entry wiring.

Spring-clamp technology provides consistent contact pressure without dependence on screw-tightening torque and automatically compensates for conductor creep. The ergonomic design provides easy front access, while integrated features such as a double jumpering system, clearly visible top marking position and test facilities help simplify panel assembly, identification, testing and maintenance.

With a rated cross-section of 1.5 mm², a rated current of 18 A and an IEC rated voltage of 800 V, the D1,5/4.2L is well suited to compact industrial wiring applications. Its narrow 4 mm pitch helps maximise DIN rail space while accommodating rigid conductors up to 2.5 mm² and flexible conductors up to 1.5 mm².

Reliable Spring-Clamp Connections for Industrial Wiring

Spring-clamp terminal technology uses resilient spring pressure to maintain secure conductor contact without relying on conventional screw tightening. This provides repeatable contact pressure and automatically compensates for conductor movement and material creep, helping maintain dependable electrical connections throughout the service life of industrial equipment.

The D1,5/4.2L combines this technology with a slim 4 mm profile and front wiring entry, making it particularly suitable for high-density control cabinets. Integrated jumpering, marking and testing provisions further simplify circuit distribution, identification, commissioning and troubleshooting.

Typical Applications

• Industrial control and automation panels.
• Machine building and OEM electrical systems.
• Feed-through conductor connections.
• Electrical distribution cabinets and switchgear.
• PLC and instrumentation panels.
• High-density DIN rail wiring assemblies.
