The role of the Slow-blow fuse：The slow-blow fuse is also called a
time-delay fuse. Its delay characteristic is maintained in the circuit
when it has a non-fault pulse current and can protect against long-term
overload. Some circuits have a current greater than a few times
the normal operating current at the switching instant. Although
this current peak is very high, it occurs for a short period of time.
We call it a pulse current or an inrush current or a surge current.
Ordinary fuses can not withstand such currents. If such a circuit
uses an ordinary fuse, it may not be able to start normally. If a larger
fuse is used, it will not be protected when the circuit is overloaded.
The melt of the time-delay fuse is specially processed to absorb
energy. By adjusting the energy absorption, it can resist the inrush
current and protect the overload.
