Generally, automatic restart is only permitted in areas that can be accessed solely by people with electrical training and qualified electricians.
However, DIN VDE 0100-530 released in June 2018 now stipulates that devices with automatic restart are also permitted in areas that can be accessed by laypersons, if the devices used meet the evaluation criteria according to DIN EN 50557 (VDE 0640-20):2012, section 4.3.2.
Our DRCCB 5 STR (Selftest Restart) meets these requirements, as it carries out a simplified insulation test using a safety extra-low voltage before the restart.
