DC isolator

Project 3 of 3

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/ IEC 60947.

Switch Disconnectors (SI) ensures 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), 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.
