Description
The BRI series thermal protector are temperature and current
protectors, which made of thermal bimetal, a high-quality thermal
sensitive material imported from Japan. This product is mainly used
for overheat overload protection of motors and electric appliances.
There are these features: quick temperature sensing, sensitive
action and reliable performance.Versatility and no need
maintenance.

Characteristics
1. Pure temperature design, small current effect
2. Epoxy sealing to ensure vacuum paint, waterproof and oil proof
3. The fully enclosed structure can prevent the components from
being polluted by dust or magazines and damaged by external forces
4. The temperature is preset before leaving the factory for the
control of a single temperature range
5. Each part strictly implements the environmental protection
standard of European ROHS
6. Shell overcurrent can be used with external casing insulation
Structure and Working Principle
This product is produced according to the thermal bimetal material
heated bending force characteristics, the butterfly double metal components for special treatment, with the increase of temperature,
butterfly storing energy device, when the temperature reaches
thermal protector rated breaking temperature, the effects of
butterfly element force moment reverse action, disconnect contact,
to cut off the circuit of protected, so as to achieve protection
function;When the temperature drops to the automatic reset
temperature of the thermal protector, the contact closes the
connection circuit and the power is restored.When the current of
the protected body exceeds the rated current, the butterfly element
generates heat energy due to the current. When the temperature of
the thermal protector is reached, the acting force generated by the
butterfly element will reverse in an instant and cut off the
circuit, thus achieving the protection function.
Applications
Widely used in submersible pumps, various DC high-power motors,
solar water heaters, heating pipes, power tools, battery packs,
fluorescent lamp ballasts, transformers, etc.
