Big Large Current Industrial BR BRI 16A 25A Temperature Protector Three-Phase Thermal Switch for Electric Motors
Description of BRI Thermal Protector
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.

Applications of BRI Temperature Protector
We manufacture thermal protectors for all kinds of motors, lamps
and lighting, transformers, cover sealing machine & various
household and industrial appliances.
Motor Protection Can Be Referred to The Following Table
| Motor insulation grade | A | E | B | F | H |
| temperature | 105°C | 120°C | 130°C | 140°C | 150°C |
Structure and Working Principle of Big Current BRI Thermal Protector
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.
