Free QuoteBUT when you switch off the amplifier, the capacitors are charged and must discharge: the discharge current pass through the fuses and if the switch-off transient opens a low impedance way, via final power transistors as example, the discharge current can open the fuse: with a memory scope measure the discharge current of the capacitors where the fuse blows.
Free QuoteInternal fuses in capacitor units There are two types of fuses used for capacitors; internal and external. When the reactive power of a capacitor unit was only a few kvar, the most natural method to protect the capacitor was with an external fuse, since in the case of a breakdown the lost reactive power was small.

Free QuoteThe internal fuses for internally fused units used in capacitor banks follow the same basic criteria, but in those cases, the fuse characteristics are applied by the manufacturer: Voltage rating – Must be larger than the capacitor unit voltage rating.
Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.
Stress specific to the protection of capacitor banks by fuses, which is addressed in IEC 60549, can be divided into two types: Stress during bank energization (the inrush current, which is very high, can cause the fuses to age or blow) and Stress during operation (the presence of harmonics may lead to excessive temperature rises).
The fuse, by its design, avoids absorbing all of the available energy on the series group. This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.
