Temperature thermal protector is made of combination of two different alloys, which will generate heat after turning on power. Due to the different thermal expansion coefficients of the two different alloys, the alloy is bound to bend in one direction, and the power is cut off when the contacts separate. The bending speed is proportional to the magnitude of the passing current. In such a process, it protects the electrical equipment.
There are various of thermal protector types. According to the nature of action: normally open normally closed. First, it is divided by use: single-phase thermal protector, three-phase thermal protector. Second, according to the material, it can be divided into: bakelite, plastic, iron shell, ceramic. Third, according to the nature of the action: it can be divided into normally open action and normally closed action.
It is a kind of thermostat using bimetal as the temperature sensing element. When the temperature drops to the set temperature, the contact automatically closes/opens, and then resume the normal working state.
Used in household appliances motors and electrical equipment, such as washing machine motors, air conditioner fan motors, transformers, ballasts, electric appliances, etc.
Please inform us that the following when order:
- Let us know the temp. Of thermal protector you are looking for
