A capacitor fuse isolates a shorted capacitor before it can damage surrounding equipment or personnel. Typical capacitor failures occur when the internal dielectric can no longer withstand the applied voltage, resulting in a low impedance current path and generating excessive heat and pressure that can cause violent case rupture.

9.1.2: Capacitors and Capacitance
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates.
CAPACITOR BANKS
If harmonic problems exist, they most often manifest themselves first at shunt capacitor banks in the form of audible noise, blown fuses or capacitor unit failures. As frequency varies, so reactance varies and a point can be reached when the capacitor reactance and the supply reactance are equal..
