What is Protective Device Testing and How is it Done
The fuse is a reliable overcurrent protective device, primarily used as a circuit protection device for over currents, overloads and short-circuits. A time-current characteristic curve, for any specified fuse, is displayed as a continuous line representing the average melting time in seconds for a range of overcurrent conditions.

Fundamentals of Capacitor Protection
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.
