Product parameters

Principle and structure

BR series thermal protector is a temperature automatic response device and is temperature, current double protective equipment as well. When the heat generated by the increasing temperature from the protected appliances transmits to double-metal element, and reaching the temperature value of scheduled movement, the double-metal element will move immediately so that the contact will be switched off and the circuit will be cut off. When the temperature decreases to the rated temperature value of reposition, bimetal element will return to its initial state, the moving contact will be closed and the circuit will be on.

 

Applications

BR series thermal protectors are connected directly in series in the main circuit of various motors which are under 0.5hp, transformers, rectifiers, electro-thermal appliances which are under 1KW and etc, as protecting equipment.

As the sensor of temperature switch, it can be applied to control circuit of various appliances. The strengthening case product can endure the pressure caused by plastic modeling. It can be applied in built-in installation in plastic-enclosed motors.
