  • Safer: The SMISSLINE TP plug-in socket system allows for load-free plugging in and unplugging under voltage without additional personal safety equipment for protection against electrical hazards.**
  • Economical: Saves time thanks to the plug-in technology and saves space thanks to the vertical installation of the bus bar socket
  • Easier: Quick maintenance of the switchboard as the wiring is already integrated into the plug-in socket system. Thus the installation is better arranged and tidier to check, even by not highly qualified personnel
  • Flexible: rapid replacement, easy expansion, and modification even under voltage as no tools are needed thanks to the snap-on installation

** Refer to your local regulations to comply with safety policies.
