RH Lightning Protection 3A 5A 10A 250V Square Electric Fan Motor Plastic Thermal Fuse Link
Description
Thermal fuse, also known as temperature fuse, is a temperature sensing circuit cut-off device.
Thermal fuse can sense the overheating generated during abnormal operation of electrical and electronic products, thereby cutting off the circuit to avoid fire. Commonly used in: electric hair dryer, electric iron, rice cooker, electric stove, transformer, electric motor, water dispenser, coffee maker, etc. The thermal fuse cannot be used again after it is operated, and it only works once at the melting temperature.
Structure
The thermal fuse is composed of plastic shell, low melting point
alloy wire, special resin, lead copper wire and sealing resin.
Apprearance
The marking must be clear; the sealing resin should fill the mouth
and it is acceptable; the lead tin-plated layer is good; there is
no oxidized black spot damage; the shell has no damage marks,
perforations, etc.
Scope of Application
electric hot water bottles, electric motors, low frequency
transformers, toroidal transformers, power adapters, circuit
boards, LED lamps, z aroma diffusers and many other household
appliances and heating appliances.
Working Principle
A piece of fusible alloy wire is connected between the two pins of
the thermal fuse, and the fusible alloy wire is covered with
special resin. The current can flow from one pin to the other pin.
When the temperature around the thermal fuse rises to it When the
operating temperature is high, it is easy to fuse and finance, and
under the action of surface tension and the help of special resin,
it shrinks into a ball and attaches to the ends of the two pins. In
this way, the circuit is permanently cut off.
