Mounts on a 40 mm busbar system per DIN 43870 Part 2 — the standard meter-panel busbar in European residential enclosures. The 1.5 width units occupy one busbar position. Infeed is via box terminal; outgoing feeder uses spring-loaded terminals for fast, tool-less wiring. The locking slide accepts padlocks, wire seals, cable ties, or Antilux for tamper-proofing. IP40 protection with connected conductors — dust-protected but not sealed; install inside a weatherproof enclosure if exposed to moisture.
