Lorentz PV Disconnects

These are simple and cost effective units used as part of a professional system installation to allow connection of PV module strings and include appropriate DC rated disconnect switch in an IP54 weatherproof enclosure.

PV Disconnect LZ-440-40-1 & LZ-440-40-6

These have provision for optional lightning surge arrestors which connects through a mounting hole in the disconnect enclosure. (Lightning surge protectors must be ordered separately).
