Product Details
Solar Isolators SI are switch gears for interupting the DC/AC-Inverter from the solar-panels. Photovoltaic-installations have to be equipped with DC-isolators according to IEC 60364-7-712.Switch Disconnectors SI ensure a reliable switching up to 32A with 1000V in the category DC21B. The construction of the contacts and the material selection guarantee that no oxidation (small switching frequency) develops, and is thus prevented inadmissible heating-up. The switching speed at the manually operated handle does not have an effect on the switching attitude of the contacts.
