PTC Resettable Fuses have been commonly used in the industry as over-voltage and over-current safety elements. By this device, the circuit can be held in a stable and safe condition after transient overload. The PTC resettable fuse, also named Polyfuse, is one of the most successful PTC product family. It has strong self-healing ability and can react to overload quickly. The PTC resettable fuse, such as the PTCTL3MR250HTE, is applied in a large range of industrial and consumer applications. The wide range of applications include power adapter, computer & server power protection, game consoles, communications equipment, LED systems, charger, battery protection, control of AC/DC circuits, lighting, electronic motor protection and many other fields. The working principle of the PTCTL3MR250HTE is based on the ability of a thermostat to change state. Specifically, when an external current flows through the device, a temperature increase occurs, thereby causing a decrease in resistance. The material used in PTC resettable fuses has positive temperature coefficient curves. As the current increases, the temperature will also increase, and in turn, the resistance of the material will also increase. When the current exceeds the rated value, the resistance will increase to the point where the device will “trip’” and the current flow will be interrupted. Once the current is turned off, the material will cool down and reset, and the device will return to its lowly resistive state. The PTCTL3MR250HTE is optimized with advanced materials and is designed with features that provide high over-current protection with high trip current accuracy. It also has a safety or short-circuit protection feature which allows it to open very quickly in the case of a short-circuit. Additionally, the device has a fast response time and a low trip temperature, allowing it to react very quickly in an overload situation. Furthermore, the device has a long life and stable characteristics, providing excellent reliability and high performance. The PTCTL3MR250HTE is easy to install and use. With its compact design, it can be installed in a small space, and the installation is very simple. The device also has an external indicator, which indicates when the device is above the rated current or when it is in short-circuit condition. In conclusion, PTC Resettable Fuses, such as the PTCTL3MR250HTE, are an effective and reliable means to protect electrical circuits from the damage of overload or short-circuit conditions. The fuse is compact, easy to install and provides high over-current protection with good trip current accuracy. As a result, PTC fuses are suitable for a wide range of industrial and consumer applications.
