1sna290379r2200 – d1.5/4.p.2l
TE Connectivity 1SNA290379R2200 D1.5/4.P.2L is a compact green-yellow two-connection spring-clamp protective earth terminal block with a 1.5 mm² nominal cross-section and screwless DIN rail grounding contact.
Why Choose the TE Connectivity D1.5/4.P.2L 1SNA290379R2200 Ground Terminal Block?
The TE Connectivity 1SNA290379R2200, manufacturer designation D1.5/4.P.2L, is a compact spring-clamp protective earth terminal block designed to provide dependable grounding connections in industrial electrical panels, automation systems and machinery. Part of the established TE Connectivity ENTRELEC SNA spring terminal block range, it combines screwless conductor termination with a direct connection to the DIN rail for reliable protective earth distribution.
The D1.5/4.P.2L features two spring-clamp connections and a green-yellow housing for immediate identification as a protective earth terminal. Its screwless rail contact is designed to provide a secure, operator-independent connection to the mounting rail, while front conductor entry simplifies wiring and provides convenient access during installation, inspection and maintenance.
With a nominal cross-section of 1.5 mm², conductor capacity up to 2.5 mm² and a rated short-time withstand current of 180 A for 1 s, the 1SNA290379R2200 provides a compact grounding solution for industrial installations. Its narrow 4 mm spacing helps maximise wiring density while maintaining a dependable protective earth connection.

Reliable Protective Earth Connections for Industrial Panels
Protective earth terminals provide an essential connection between equipment conductors and the grounded DIN rail within an electrical enclosure. The D1.5/4.P.2L uses a screwless rail contact to establish this connection while its spring-clamp conductor terminals maintain contact pressure without relying on installer-applied screw torque.
The compact 4 mm profile makes the 1SNA290379R2200 particularly useful where many grounding connections must be accommodated within limited DIN rail space. Its green-yellow housing, front wiring access and spring-clamp technology provide a practical combination of identification, installation efficiency and dependable protective earth connectivity.
Typical Applications
- Protective earth connections in industrial control panels.
- PLC and automation control cabinets.
- Machine building and OEM electrical systems.
- Industrial machinery grounding circuits.
- Process control and instrumentation panels.
- High-density DIN rail protective earth installations.
