1sna290001r0400 – d2.5/5.2l.2l grey
TE Connectivity D2.5/5.2L.2L 1SNA290001R0400 is a grey 5 mm-wide spring-clamp feed-through terminal block with two separate circuits, four connections, a 24 A rated current and an 800 V rated voltage for 35 mm DIN rail installations.
Why Choose the TE Connectivity D2.5/5.2L.2L 1SNA290001R0400 Spring Terminal Block?
The TE Connectivity / Entrelec D2.5/5.2L.2L 1SNA290001R0400 is a compact grey spring-clamp feed-through terminal block from the SNA range, designed for reliable conductor connection in industrial control panels, machinery and electrical distribution assemblies. Its spring connection technology provides consistent contact pressure without relying on installer-applied screw torque.
Designed with two separate feed-through circuits and four connection points, the D2.5/5.2L.2L enables multiple connections within a compact 5 mm-wide terminal footprint. Front-entry wiring provides convenient conductor access, while the spring-clamp mechanism supports efficient installation and automatic compensation for conductor settling over time.
The 1SNA290001R0400 is rated at 24 A and 800 V under IEC specifications and accepts flexible conductors from 0.12–2.5 mm² and rigid conductors from 0.12–4 mm². Designed for 35 mm DIN rail mounting, it combines compact dimensions with practical testing and jumpering capabilities for professional panel-building applications.

Reliable Spring-Clamp Connections for Industrial Wiring
Spring-clamp terminal technology maintains conductor contact through a mechanically applied spring force rather than installer-controlled screw torque. This helps provide repeatable connection pressure while reducing the need for routine retightening, making spring terminals particularly suitable for control panels and machinery exposed to demanding operating conditions.
The D2.5/5.2L.2L combines this connection method with two separate feed-through circuits and four connection points. Its compact 5 mm spacing, front wiring access and DIN rail mounting make it well suited to high-density industrial wiring where installation efficiency, circuit accessibility and dependable electrical connections are important.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Machine-building electrical systems.
- Instrumentation and process-control wiring.
- Power and signal distribution assemblies.
- DIN rail-mounted terminal strips.
