Can a capacitor be used for overvoltage protection?
A capacitor is not a fuse. Unlike a fuse it is undocumented how a capacitor fails. What I mean to say is: - when a fuse fails, it breaks the circuit and the circuit it safe. - when a capacitor fails, it may either break the circuit or short it. …

This type of protection may be assigned to the capacitor itself, but it is generally a type of overall electrical system protection. Given that the capacitor can generally accommodate a voltage of 110% of its rated voltage for 12 hours a day, this type of protection is not always necessary.
Capacitor Types [Use Cases + How to Choose the Right One]
Capacitors are integral electronic components, and they come in diverse types.Each type is specifically designed for certain applications. The capacitor market has shown remarkable growth, reaching a global valuation …
Fusing and Protection The main purpose of the fuse on a capacitor bank is to clear a fault if a capacitor unit or any of the accessories fail. The fuse must clear the fault quickly to prevent any of the equipment from failing violently. Ruptures of capacitors have historically been problematic, so fusing is normally

The capacitor bank protection fuse-links are described in IEC 60549 (High-voltage fuses for the external protection of shunt capacitors) [3]. Also in this case the fuse should meet the requirements described in the general standard IEC 60282-1 [2], with additional
In order to prolong the life of the fuse, the circuit designer should ensure that the load on the fuse does not exceed the nominal rating listed by the manufacturer. So a fuse with a current rating of 10A would not be recommended for operation at more than 7.5A in a 25°C ambient temperature.
