2JS 300

2JS 300 is a type of fuse which utilizes a two-dimensional electric current technology. This technology combines a vertical current and a horizontal current in a single device. It allows for the protection of sensitive equipment and circuits against overloads, short circuits and localized heat extremes. It is most commonly used in consumer, automotive and industrial applications, as well as in applications involving multiple voltage sources.The working principle of the 2JS 300 fuse is quite simple. It consists of two electrodes, one made of metal and the other one of plastic. These electrodes are held together by a set of metal springs. When an overcurrent occurs, the current travels through the metal electrode and heats up the surrounding springs. This causes the plastic electrode to expand, which in turn releases the springs and breaks the circuit, effectively interrupting the current.The 2JS 300 fuse has a number of applications in consumer and automotive electronics, such as protecting the circuit board from high current surges, or the battery voltage from overcharging. It can also be used in industrial applications, such as welding and compressor protection, as well as in multiple voltage sources.The 2JS 300 fuse is an incredibly versatile piece of technology that provides excellent protection from electrical overloads and localized heat extremes. It has a wide range of applications in consumer, automotive and industrial electronics, as well as in applications involving multiple voltage sources. It is a relatively inexpensive way to protect vulnerable parts of an electrical system, ensuring a long and reliable life.
