1sna290383r0700 – 1.5mm blue spring clamp
TE Connectivity 1SNA290383R0700 D1.5/4.N.4L is a blue 1.5 mm² four-connection spring clamp feed-through terminal block rated at 18 A and 800 V for DIN rail industrial wiring applications.
Why Choose the TE Connectivity 1SNA290383R0700 Spring Clamp Terminal Block?
The TE Connectivity 1SNA290383R0700, type D1.5/4.N.4L, is a blue 1.5 mm² spring clamp feed-through terminal block designed for reliable conductor connections in industrial control panels, machinery and automation systems. Part of the established Entrelec terminal block range, this compact DIN rail terminal provides four connection points with front-entry spring clamp technology.
Spring clamp technology provides consistent contact pressure independently of the installer, helping maintain a secure electrical connection without routine screw retightening. The front wiring entry simplifies conductor access inside densely populated control cabinets, while the terminal's vibration-resistant connection principle makes it particularly suitable for industrial machinery and automated equipment.
The D1.5/4.N.4L has a 1.5 mm² nominal cross-section, 18 A rated current and 800 V rated voltage. Its narrow 4 mm pitch supports high-density panel wiring, while the blue housing provides clear circuit identification and is commonly suited to neutral conductor applications.

Reliable Spring Clamp Connectivity for Industrial Panels
Spring clamp terminal blocks provide a dependable alternative to conventional screw terminals by applying continuous spring pressure to the conductor. This helps compensate for conductor movement and material settling while providing excellent resistance to vibration and mechanical shock, making the technology well suited to machinery, transportation and industrial automation environments.
The TE Connectivity D1.5/4.N.4L combines this connection technology with a compact four-connection format. Front conductor entry, double jumpering capability, visible marker locations and test accessory compatibility help simplify panel assembly, inspection and maintenance while supporting space-efficient DIN rail installations.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine control and factory automation systems.
- Neutral conductor distribution and identification.
- Instrumentation and signal wiring.
- Power distribution and control circuits.
- OEM machinery and panel building.
- DIN rail terminal assemblies.
