Why Choose the TE Connectivity D35/16.NT.L 1SNA399892R2700 Neutral Disconnect Terminal Block?

The TE Connectivity D35/16.NT.L 1SNA399892R2700 is a blue spring-clamp neutral disconnect terminal block developed for reliable neutral conductor connection and isolation in industrial electrical distribution systems. Its design is particularly suited to TN-C-S networks, providing convenient neutral disconnection when isolation, testing or maintenance is required.

The D35/16.NT.L uses spring-clamp connection technology, providing consistent conductor contact pressure independent of the installer while automatically compensating for conductor creep. Front wiring entry makes conductor installation and maintenance readily accessible, while the terminal's closed construction means that no separate end section is required.

With a 125 A rated main-circuit current, 4 kV impulse withstand voltage and robust 16 mm-wide housing, the D35/16.NT.L is designed for substantial neutral distribution applications. It mounts on standard TH35 DIN rail and provides a practical combination of high-current capability, disconnect functionality and spring-terminal reliability.

Reliable Neutral Isolation with Spring-Clamp Technology

Neutral disconnect terminals provide a convenient means of isolating the neutral conductor during electrical testing, commissioning and maintenance. The D35/16.NT.L is specifically designed for this role in TN-C-S networks, allowing the neutral connection to be disconnected without dismantling the surrounding terminal assembly.

Its spring-clamp system maintains contact pressure without relying on installer-applied screw torque and automatically compensates for conductor creep. Combined with accessible front wiring and a closed housing that requires no additional end section, this provides an efficient solution for high-current neutral distribution within professional electrical panels.

Typical Applications

  • TN-C-S electrical distribution networks.
  • Neutral conductor distribution and isolation.
  • Industrial electrical control panels.
  • Power distribution cabinets.
  • Machine-building electrical systems.
  • Industrial automation installations.
  • Electrical testing and commissioning systems.
  • DIN rail power terminal assemblies.
