A PTC resettable fuse, such as B59830C80A70, is electrical protective equipment commonly found in charging applications and industrial machinery. PTC resettable fuses can protect connected components from electrical surges and accidental damage by disconnecting the electrical load when an unsafe current is detected. They differ from one-time fuses in that they resume the electrical current flow once the current drops to a safe level. PTC resettable fuses can be found in almost all industries, from household appliances and electronic devices to electric vehicles and industrial machinery.

PTC resettable fuses are typically made out of two components, a positive temperature coefficient (PTC) thermistor and a bimetallic strip. The thermistor is designed to detect changes in temperature due to a current surge and react to protect the circuit. The bimetallic strip causes the thermistor to open when a specific temperature is reached. When the current drops to a safe level, the thermistor and bimetallic strip reset the circuit and allow the current to flow again.

The most common application of a PTC resettable fuse is in the protection of electronic circuits. The fuse functions by disconnecting the circuit when it detects an unsafe current, protecting components from damage or malfunction. The fuse can be used in many different types of electrical equipment, including home appliances, medical equipment, computer motherboards, and automotive electronics.

A PTC resettable fuse is also commonly used on electric vehicles as both a safeguard and as an emergency backup when the main motor fails. The fuse acts as an additional layer of protection by larger, permanent fuses. If the main fuse does not protect the circuit, the PTC resettable fuse can intervene by automatically disconnecting the circuit and protecting the vehicle from further harm.

Aside from charging applications and electric vehicles, a PTC resettable fuse can also be used in a variety of other industries. In industrial applications, the fuse can act as a solution for protecting motors, pumps, and other electrical equipment. In medical devices, the fuse can help in the identification of fault current and to act as a protective element against harmful electric shocks or fires. The fuse can also be used in the aviation and defense industries, helping to protect sensitive equipment from power surges or other unexpected occurrences.

Overall, PTC resettable fuses, like the B59830C80A70, provide a versatile and reliable method of protecting electronic circuits from an unexpected surge or malfunction. It is a cost-effective way to ensure the safety of components and electrical circuits, and it is easy to use and reset when needed. The fuse can be found in a variety of different settings, from automotive vehicles and household appliances to medical devices and sensitive equipment in the aviation industry.
