Intelligent construction, lots of practical details.

The benefits of the new arrestor series lay in its countless, well thought-out components. They can be installed without any problems with just a few actions. The high-quality material and the intelligent construction allow their use, even with high mechanical loads.

  • Safe handling Reliable, vibration-free locking through acoustic feedback (CLICK), comfortable handling through ergonomic handle surfaces
  • Incorrect insertion protection For safe insertion of the covers
  • Optimised rating plate QR code for full traceability of each arrestor cover with web address stored for additional user information.
  • Soft release contacts Newly developed soft-release contacts in combination with a locking mechanism protect the covers of the protection elements even under the harshest mechanical strains. The wedge-shaped design of the contacts allows simple attachment of the covers.
  • Voltage and type coding For unmistakable assignment of the cover and base of the arrestors
  • High-quality materials The halogen-free and UL-listed plastic material fulfils the newest standards in installation technology.
