Principle of current overload protection:
The current flows through the moving contact terminal/bimetallic sheet, and is then formed by connecting the static contact terminal to an electrical appliance (such as a battery) . Circuit, when the current of the electrical appliance exceeds the tripping value set by the protector, the protector will Cut off the power supply in the room to protect the electrical appliances;

Temperature protection principle:
The current flows through the moving contact terminal/bimetallic sheet, and is then formed by connecting the static contact terminal to an electrical appliance (such as a battery).Circuit, when abnormal operation of the electrical appliance causes the surrounding temperature to be too high, heat is transferred to the bimetallic sheet for correction.The excessive tripping temperature causes the electrical contacts to quickly disconnect and cut off the circuit. When the temperature drops to the reset temperature, the double metal.The component resets and quickly closes the electrical contact connection circuit, continuing the cyclic action.
