1sna290322r0100 – d2,5/5,ntlp,l
TE Connectivity 1SNA290322R0100 D2,5/5.NTLP.L is a compact 2.5 mm² multi-level spring-clamp installation terminal block rated at 20 A with neutral isolation functionality for professional TN-C-S and DIN rail wiring applications.
Why Choose the TE Connectivity D2,5/5.NTLP.L 1SNA290322R0100 Spring Installation Terminal Block?
The TE Connectivity 1SNA290322R0100, type D2,5/5.NTLP.L, is a compact multi-level spring-clamp installation terminal block from the TE Connectivity / ENTRELEC SNA range. Designed specifically for installation wiring and TN-C-S network applications, it combines multiple circuit functions within a narrow 5 mm terminal width to maximise available DIN rail space.
The D2,5/5.NTLP.L incorporates spring-clamp connection technology that maintains consistent contact pressure independently of installer-applied torque and automatically compensates for conductor creep. Front wiring access simplifies conductor insertion and servicing, while the integrated neutral arrangement supports convenient neutral isolation in suitable installation circuits.
With a nominal cross-section of 2.5 mm², a main-circuit rated current of 20 A and a rated impulse withstand voltage of 4 kV, the 1SNA290322R0100 is engineered for professional electrical distribution and control installations. Its compact multi-level construction combines grey, blue and green-yellow functional identification within a single DIN rail terminal assembly.
