FAQ
Q: What is the breaking capacity of a fuse?
A: Value of prospective current that a fuse is capable of breaking at a stated voltage under prescribed conditions of use and behaviour.
Q: What is the arcing time of a fuse?
A: Interval of time between the instant of the initiation of the arc in a fuse and the instant of final
arc extinction in that fuse.
Q: What is the operating time of a fuse?
A: Sum of the pre-arcing time and the arcing time.
