Features:
● The 7AM thermal protector is manufactured with proprietary Klixon technology from Texas Instruments USA. It serves as a protection component against overheating and overload of electrical appliances and motors.
● Working principle of 7AM thermal protector: Electric current flows through the Klixon bimetallic strip and contacts. When abnormal operation causes excessive ambient temperature or overcurrent, the bimetallic strip reacts quickly and disconnects the circuit once the temperature reaches the tripping threshold. When the temperature drops to the reset value, the Klixon bimetallic strip automatically closes rapidly.
