1 Product description Of The 1A 2A 3A 5A 10A 15A 16A 250V Temperature Thermal Cutoff Fuse
A thermal fuse or thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would.
Y series thermal fuse introduction: thermal fuse is composed of fuse wire and insulated shell, mainly used in electrical and electronic product equipment and its parts. It is mostly used in indoor electrical equipment, mainly to protect electrical equipment from overheating under abnormal conditions. Once the fuse is to be reset, only the temperature fuse of the same type and specification can be used.
2 Working principle Of The 1A 2A 3A 5A 10A 15A 16A 250V Temperature Thermal Cutoff Fuse
When the temperature of the equipment rises abnormally, the thermal fuse is induced to heat, and when the temperature reaches the set temperature of the alloy, the low melting point is melted, and the surface tension of the molten alloy increases under the action of the special resin, causing the alloy to shrink in a spherical shape. On the lead wire, the circuit is completely cut off.

4 Product installation guidelines Of The The 1A 2A 3A 5A 10A 15A 16A 250V Temperature Thermal Cutoff Fuse
* Keep a distance of 3mm from the fuse body when bending the wire.
* When welding or soldering exceeds the rated temperature of the fuse, the longer the welding distance and the shorter the welding time, the less damage to the fuse.
* Be careful of the current flowing in the insurance body.
* Do not use liquids or toxic gases such as sulfuric acid and nitric oxide.
* Do not connect the heater and the fuse directly.

10 What are the characteristics of the Thermal Fuse?
Thermal
fuse
has
the
characteristics
of
accurate
melting
temperature,
high
withstand
voltage,
small
size
and
low
cost.
The
thermal
fuse
shell
is
marked
with
the
rated
temperature
value
and
the
rated
current
value,
it
is
not
difficult
to
identify,
and
it
is
very
convenient
to
use.
It
can
be
widely
used
in
electrical
equipment,
electric
heating
equipment
and
practical
electrical
appliances
for
overheating
protection.
Thermal
fuse
mainly
has
the
following
parameters:
①
Rated
temperature:
Sometimes
called
the
operating
temperature
or
fusing
temperature,
it
refers
to
the
temperature
at
which
the
temperature
rises
to
the
fusing
temperature
at
a
rate
of
1°C
per
minute
under
no-load
conditions.
②
Fusing
accuracy:
refers
to
the
difference
between
the
actual
fusing
temperature
of
the
thermal
fuse
and
the
rated
temperature.
③
Rated
current
and
rated
voltage:
Generally,
the
nominal
current
and
voltage
of
thermal
fuse
have
a
certain
margin,
usually
5A
and
250V.
Thermal
fuse
is
a
one-time-use
protection
element.
Its
use
affects
not
only
depends
on
the
performance
of
the
element
itself
but
more
importantly,
on
how
to
select
and
install
the
thermal
fuse
correctly.
The
thermal
fuse
is
generally
connected
in
series
in
the
circuit
when
it
is
used.
Therefore,
when
choosing
a
thermal
fuse,
its
rated
current
must
be
greater
than
the
current
used
in
the
circuit.
Never
allow
the
current
through
the
thermal
fuse
to
exceed
the
specified
rated
current.
Before
selecting
the
rated
temperature
of
the
thermal
fuse,
you
must
understand
and
measure
the
temperature
difference
between
the
temperature
to
be
protected
and
the
location
where
the
planting
fuse
is
installed.
In
addition,
the
length
of
the
fusing
time
and
the
availability
of
ventilation
are
also
closely
related
to
the
selection
of
the
rated
temperature
of
the
thermal
fuse.
