Particularly with sensitive applications, the internal protective devices of the capacitors must be supplemented by the user with suitable external protective mea-sures. External protective measures are even mandatory when capacitors are used without internal protective devices.
Capacitor Bank Protection Definition: Protecting capacitor banks involves preventing internal and external faults to maintain functionality and safety. Types of Protection: There are three main protection types: Element Fuse, Unit Fuse, and Bank Protection, each serving different purposes.
Even if the test based on the capacitor standard is passed, this does not ensure comprehensive protection against all pos-sible overloading. Currently, a number of customers are requesting special tests on unprotected capacitors with extreme overvoltages and temperatures to prove safe capacitor per-formance.

Subclass X2 and Y2 are the most common type of subclass for applications that use 120VAC (USA) or 220/240VAC (Europe). X/Y combination capacitors are also available, so you might consider using one of these, as well. Whichever safety capacitor you choose, make sure that it has all the proper safety-approval logo markings.
There are mainly three types of protection arrangements for capacitor bank. Element Fuse. Bank Protection. Manufacturers usually include built-in fuses in each capacitor element. If a fault occurs in an element, it is automatically disconnected from the rest of the unit. The unit can still function, but with reduced output.
Voltage Sag Protection | Advanced PCB Design Blog | Cadence
These measures can help minimize downtime and associated costs. Voltage Sag Protection and PCB Design. PCB design can be affected by voltage sag protection measures, especially when dealing with sensitive or critical electronics. Including voltage sag protection in PCB design considerations can help make the product more reliable and robust.
Fundamentals of Adaptive Protection of Large Capacitor Banks
