1sna399586r2400 – d4/6,nt,l
TE Connectivity 1SNA399586R2400 D4/6.NT.L blue neutral disconnect terminal block with spring-clamp connection, 4 mm² rated cross-section and 32 A rated current for industrial electrical installations.
Why Choose the TE Connectivity 1SNA399586R2400 D4/6.NT.L Neutral Disconnect Terminal Block?
The TE Connectivity 1SNA399586R2400 is a compact D4/6.NT.L neutral disconnect terminal block from the Entrelec terminal block range, designed to provide a reliable and easily accessible neutral connection in electrical panels and industrial automation systems. Its spring-clamp connection provides secure conductor retention while allowing straightforward installation without conventional screw-clamp wiring.
Designed for 4 mm² conductors, the D4/6.NT.L provides a dedicated neutral disconnect function and is particularly suited to TN-C-S electrical networks. The disconnect arrangement allows the neutral circuit to be isolated conveniently for testing, maintenance or electrical isolation while the front wiring entry provides easy access during installation.
The terminal block has a compact 6 mm spacing and mounts onto standard TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715. Its blue housing provides clear identification of the neutral circuit, while the spring connection system provides consistent clamping pressure independent of the operator.
