Electric motors are workhorses in industrial, commercial, and residential applications. From powering machinery in factories to driving compressors in air conditioners and refrigerators, motors are critical to modern life. However, they are also susceptible to one of the most common causes of failure—overheating. To prevent this, engineers implement various thermal protection devices, and among them, the thermal protection fuse plays a vital role. But what exactly is a thermal protection fuse on a motor, and how does it work?
