Cutoff Fuse for Fan Motor
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.

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.
