These disconnect switches comply with ieC 60947-3 and VDe 0660 part 107 standards. These are real d.c. switches, specially designed for PV applications. HelioProtection® switches are complete compact products, and are delivered already assembled with their shunts (so there's only one catalog number for the whole unit!). Connections are IP20 rated finger safe. HelioProtectio® switches are fitted to be mounted directly on a DIN rail. They must be installed and tested by qualified personnel with thorough knowledge of the rules governinginstallation in PV applications.
