When a capacitor bank unit breaks downthe, remaining capacitors in the same parallel group hold some amount of charge. The charge will disappear in a form of a high frequency transient current that goes through the broken down capacitor unit and its fuse. The fuse holder and the broken down capacitor unit should resist this discharge transient.
When a capacitor bank unit fails, other capacitors in the same parallel group contain some amount of charge. This charge will drain off as a high frequency transient current that flows through the failed capacitor unit and its fuse. The fuse holder and the failed capacitor unit should withstand this discharge transient.
