System joint box in the case of road lighting system failure

  • Group searches are made possible by configuring a master joint box and a slave joint box, and the time required to respond to failures is significantly reduced by routinizing the work
  • Improvement from the conventional screw terminal connection method to lever-operated isolation method significantly reduces work when a failure occurs
  • High waterproof and dustproof functions maintain long-term performance under harsh conditions in the outdoor field
  • Dedicated SPD (JIS Class II compliant) can be installed as an option for reliable protection from lightning
    (Mega ring test is possible with SPD mounted)
