- prIEC 61643-41 compliance
The DDC50S-21Y range is type 2 pluggable surge protectors designed for protection to Energy System Storage (ESS).
Its technology based on high energy varistor equipped with thermal disconnection mechanism offers protection efficiency and and a maximal reliability.
These DC power surge protectors are available with a Max. DC operating voltage from 500 to 1500 Vdc.
To ensure maximum protection of the ESS installation, CITEL has developed a kit (article code: 1156339601) of products consisting of a DDC50S-21Y surge protector and a specific fuse (100,000 A tested and approved) compatible with: short-circuits of storage systems and CITEL surge protectors.
