Selection Table Of The Time Lag Subminiature Fuse
Can fast-acting fuse replaced by slow blow fuse ?
The two can replace each other in some circuits with less stringent
requirements, but cannot replace each other in circuits with strict
requirements.
T2A is a slow blow fuse and F2A is a fast blow fuse. The main
difference between a slow-blow fuse and a fast-blow fuse is its
ability to withstand instantaneous pulse current, which means that
it can resist the impact of surge current when switching on and off
without moving, thus ensuring the normal operation of the
equipment, so slow-blow fuses Often referred to as a surge fuse.
From a technical point of view, slow-blow fuses have a larger
melting heat value and require a larger amount of energy to fuse.
Therefore, for fuses with the same rated current, slow-blow fuses
are much more resistant to pulses than fast-blow fuses.
Since the thermal energy value of the slow-blow fuse is larger than
that of the fast-blow fuse of the same specification, the fusing
time will be slower than that of the fast-blow fuse when an
overcurrent occurs in the circuit.
Once the circuit fails, the overcurrent will not disappear by
itself. The energy of the continuous overcurrent will greatly
exceed the thermal energy value of the fuse. No matter what kind of
fuse will be blown, the time difference between slow blowing and
fast blowing is important for its protection requirements. It is
not very important, only when there are sensitive devices in the
protected circuit that need to be protected, slow fuse will have an
impact on the protection performance.
Because of these differences, slow-blow fuses and fast-blow fuses
are used in different circuits: pure resistive circuits (no or
little surge) or circuits that need to protect sensitive and
valuable components such as ICs must use fast-blow fuses; For
capacitive or inductive circuits (there is a surge when switching
on and off), it is best to use slow-blow fuses in the input/output
parts of the power supply; in addition to protecting IC circuits,
slow-blow fuses can be used in most situations where fast-blow
fuses are used. It improves the anti-interference ability; on the
contrary, if the fast-blow fuse is used in the place where the
slow-blow fuse is used, it will often cause the phenomenon that the
instant-blow fuse cannot work normally.
