ArcBox

Making solar even safer in just two clicks!

Electric arcing results in incredibly high temperatures. The ArcBox enclosure simply snaps around a DC connector to ensure that if an arc ever occurs, it is safely contained and doesn't spread to combustible materials in or around the solar installation.

Key applications

  • BIPV Solar 
  • Combustible Roofs
  • High-Consequence Locations

Making Solar PV even safer!

The number of solar installations is growing fast and with it the risk that mistakes assembling DC connectors lead to fires. Simple errors in installation that can cause an arc fault to develop include: poorly crimped joints, cross-mating connectors from different manufacturers, assembling electrodes while wet and incomplete insertion that doesn’t engage the connector locking mechanism.
