Preset calibration temperature ; not adjustable in the field.

Case electrically alive; insulating sleeving is available.


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.




Pump, high power motor

Heating tube

Electric tool, battery packs
