PTC resettable fuses, also known as polyfuses, are a type of polymeric positive temperature coefficient (PPTC) fuse used as a safety device in electronic circuits. They are reset using either a mechanical means (such as a button) or an internal reset circuit. Although PTC resettable fuses are not as fast-acting as traditional fuses, they are ideal for use in applications where a reset capability is desired.

One of the most popular PTC resettable fuses available on the market is the 0ZCA0020FF2E. The datasheet for this PTC resettable fuse states that it is capable of safely interrupting current up to 20A and withstanding voltages up to 32V. It is a low resistance, highly reliable, and easy to use fuse.

The 0ZCA0020FF2E PTC resettable fuse is designed for a wide range of applications, from DC to AC power supplies. Some of the more common applications of this PTC resettable fuse include industrial equipment, consumer electronics, automotive, electric scooters, LED lighting, and robotics. It can be used in a wide range of environments, including hazardous and explosive areas such as mines, oil rigs, and military bases.

The working principle of the 0ZCA0020FF2E PTC resettable fuse is relatively simple. The fuse element consists of two small cylindrical metal parts that are connected by a metal spring. The two metal parts are separated by a polymeric material which quickly melts when it reaches a certain temperature. When current is applied to the two metal parts, the polymeric material heats up and melts, thus increasing the resistance of the circuit. This increase in resistance causes the current to drop, and the fuse element to trip. The fuse element can then be reset by manually pressing the reset button on the fuse or using an internal reset circuit.

The 0ZCA0020FF2E PTC resettable fuse is a very effective and reliable safety device for many applications. It is easy to install and use, and offers protection against over current and voltage. It is a low cost and reliable solution for many applications in which a reset capability is desired.
