PTC Resettable Fuses are an innovative type of fuses that can reset themselves after they have tripped. The 0ZRB0300FF2B is one such type of fuse and it is commonly used in a wide variety of fields. This article will explain the application field of the 0ZRB0300FF2B as well as its working principles.

The 0ZRB0300FF2B is a common type of PTC resettable fuse and it is typically used for protecting electrical circuits and components from damage caused by a variety of causes. This type of fuse is usually used as a back-up protection device since it can reset itself after the fault has been corrected. It is often used in a variety of applications including automobile, home appliances, solar systems, power distribution, industrial, lighting, and more.

The 0ZRB0300FF2B is made up of a polymer-based body and two metal plates that are connected by a bimetal strip. The strip is heated by the current that passes through the device. When the current that passes through the fuse increased to the rated current, the bimetal strip will begin to heat up and expand. When it expands enough, it will cause the metal plates to break apart and thus open the circuit. This is why the device is called a "fuse."

Once the current has been reduced to below the rated level, the bimetal strip will cool down and contract. This will cause the plates to move back together and thus re-close the circuit. This resetting action is why these types of fuses are known as "resettable."

The 0ZRB0300FF2B can be used in a variety of applications where other types of fuses are not appropriate. For example, in applications where the rated current level is constantly changing, the PTC resettable fuse can reset itself repeatedly without having to be replaced. Another application for the 0ZRB0300FF2B is in automobile applications where the device can provide protection for the entire electrical system from short-circuits and overloads. Finally, the device can also be used in a variety of other applications where a fuse is needed but other types are not suitable.

The working principle of the 0ZRB0300FF2B is quite simple. When the current level reaches the rated current level, the metal plates will break apart and open the circuit. Once the current level is reduced, the bimetal strip will cool down and cause the metal plates to move back together, thus re-closing the circuit. This process can repeat itself as many times as necessary, providing protection from overcurrent and short-circuits.

In conclusion, the 0ZRB0300FF2B is a common type of PTC resettable fuse that can be used in a variety of applications. It is designed to reset itself after the fault has been corrected and can provide protection from overcurrent and short-circuits. It can be used in a variety of applications including automobiles, home appliances, solar systems, and more. Understanding the application field and working principles of this device will help users select the best type of fuse for their specific application.
