Manufacturing thermal protectors and switches since 2010.

Thermal protector,thermal Switch Series

Thermal protector Thermal switch is a kind of temperature switch which uses bimetallic sheet as temperature sensing element. When the electrical appliance works normally, the bimetallic sheet is in the Free State, and the contact is in the closed/open state, when the temperature rises to the operating temperature value, the bimetallic element acts quickly due to internal stress caused by heating. Open/close the contact and cut off/connect the circuit, thus playing a role of thermal protection. When the temperature drops to the reset temperature, the contact automatically closes/disconnects and returns to the normal working state. Widely used in household electrical appliances and electrical equipment, such as washing machine motor, air conditioning fan motor, transformer, ballast, electric heating appliances, etc.


HCET-A bimetal temperature  switch  thermostat  manufacturer in China
HCET-A/TB02 series bimetal temperature  switch  thermostat Snap action devices are most often used for temperature limiting applications as their fairly wide differential between opening and closing temperature provides slower cycling characteristics.  We have been able to control the amount of differential in many of our snap action controls, that enables them to be used for temperature control applications.
HCET-A-S01  series thermal protector  temperature limiter replace thermik s01
HCET Key Benefits:The first China-made round shape thermal protector got UL, TUV and CQC certifications and broke 30 years’ monopoly of German protectors.Thermal protection  HCET-A-S01 is in a well-sealed design,which can prevent product failure from the vacuum impregnation process.Thermal protection switch is Small in size and suitable to be embedded inside the coil of electric motors.motor thermal overload switch with a metal casecan bear up to 50KG coil shaping pressure, which has high thermal conductivity and temperature sensitivity.Pure temperature action type products, bimetal-disc without current and heat effect, accurate temperature control.
