Why does TCO function during process of heat-shrinkable tubing? How to avoid this kind of situation?
During
the
process
of
heat-shrinkable
tubing,
the
lead
wires
should
feel
the
heat
and
transfer
the
heat
to
the
thermal
alloy.
TCO
functions
when
the
temperature
is
high
enough.
Please
pay
attention
that
high
temperature
or
long
time
of
tubing
may
damage
TCO
or
cause
TCO
to
function.
In
order
to
avoid
the
damage,
it
is
proposed
that
customers
check
their
technique
of
tubing.
Please
refer
to
the
question
“Why
do
TCO
function
in
large
volume
when
they
are
applied
in
the
appliance
and
put
in
the
oven
for
baking?”.
If
you
are
using
air
heater
during
the
process,
please
guarantee
the
distance
and
time
is
reasonable
to
ensure
the
heat
transferred
to
the
TCO
would
not
exceed
its
functioning
temperature.

FAQ Of The Thermal Cutoff Fuse Links 16A 250V 115℃
| Can thermal cutoff (TCO) be used as current fuse? | No. TCO is only sensitive to temperature, so please use TCO strictly under its rated current and voltage. |
| Can TCO be put in the liquid or gas environments? |
No. Considering the technique of TCO, it is not allowed to be used under environment of liquid, just as water or organic solutions, as well as the humid condition. It cannot be applied in the environment of corrosive gas (such as sulfur dioxide,hydroxide) either. |
| When TCO is riveted, there is no heat source. How could TCO fuse off when the whole appliance is under testing? | This could be caused by the highvalue of contact resistancein the riveting position. When loading the current, the riveting position would generate heating due to high contact resistance and transfer to TCO. When the temperature rises to the rated Tf, it will function and cut off the circuit. |
| How to install TCO to achieve the optimal performance? |
There
are
two
ways
for
TCO
to
sense
the
temperature. 1. The TCO body needs to be put close to the heat source. TCO feels the temperature through the body. As the body of TCO (alloy type)has no direct contact with the thermal alloy, it takes more time when the heat from the body transfer to the thermal alloy. The heat transfer rate is slow in the kind of installation. The fusing off action would come in with delay. 2. The lead wires of TCO need to be put close to the heat source or to be connected with the heat source directly. TCO feel the temperature through the lead wires. As the lead wires are connected to the thermal alloy directly, thermal alloy could feel the heat source once the lead wires feel it. Because the lead wires are no insulated, it is suggested that customers to put good heat transfer and good withstand voltage bushing outside of the them.PS: TCO is not allowed to be suspended inside of the equipment. |
| Can TCO bear tension or pressure? What is the parameter? | The case, epoxy and lead wires could not be pulled or pushed no matter when it is installed under the normal temperature or when it is used under environmental temperature. These actions could damage the internal sensing temperature part of TCO. |
| How to test the functioning temperature when conducting IQC inspection? |
If
you
have
a
silicon
oil
bath
for
testing
TCO’s
functioning
temperature.
Please
pay
attention
to
below
tips:
1.
The
current
passing
TCO
is
less
than
10mA.2.
Put
the
TCO
into
the
silicon
oil
bath
at
a
point
of
Tf-12℃.(For
example,
TCO
of
A4-F
series
should
be
put
into
the
silicon
oil
bath
when
the
temperature
reach
118℃).
You’d
better
keep
the
temperature
constant
for
about
30
minutes. 4.The probe should be attached to the TCO as close as possible. You could use a constant temperature oven with the blowing device to do the test if you don’t have a silicon oil bath. When using a constant temperature oven Please pay attention to: a. Put the TCO into the silicon oil bath at a point of Tf-12℃. You’d better keep the temperature constant for about 30 minutes. b. To ensure the accuracy of temperature inside of the oven, you’d better put the TCO into the oven together with a probe. c. The temperature of silicon oil bath rise at a rate of 0.5-1℃ per minute till the TCO fuse-off.The rate of heating up can not exceed 1℃ per minute after putting in the TCO |
