Overview

The comprehensive protection device 7SJ6212-4EB22-3HH0 $r $nSICROWBAR AC overvoltage protection device is used to protect the power semiconductor devices (thyristors and diodes) inside the converter and prevent phase to phase overvoltage on the three-phase power supply. The scope of application is not limited to protecting DC drive converters, but can also be used for feeding and regenerative feedback devices in AC drive systems equipped with thyristors. The overvoltage that occurs on the AC side of the converter is mainly caused by the switching operation when disconnecting the power supply from the primary side of the transformer. This applies to operational switch operations (no-load shutdown) and on/off operations during faults (load shutdown)
