Fuses are specified to interrupt within a maximum of 5 seconds when
driven at 200% of their rated current for nominal ratings up to and
including 10 amperes. A fuse with a nominal rating of 15 amperes is
specified to interrupt within a maximum of 10 seconds when driven at 200%
of its rated current. The power supply shall be capable of delivering
appropriate levels of current to achieve short fusing times. There is an
additional derating of 0.2%/°C for an increase in the temperature of
fuse body.
