NATO Supply Class 5920 is a classification within NATO Supply Group 59, which is dedicated to Electrical And Electronic Equipment Components.

Class 5920 specifically includes fuses, arrestors, absorbers, and protectors. These components play a crucial role in electrical and electronic systems by protecting them from overcurrent, overvoltage, and other electrical disturbances.

Fuses are devices that are designed to break the circuit when excessive current flows through them, thus protecting the equipment from damage. They are commonly used in electrical systems to prevent fires and other hazards.

Arrestors, on the other hand, are used to protect electrical equipment from overvoltage surges. They divert the excess voltage to the ground, preventing it from damaging the equipment.

Absorbers are components that absorb or dissipate electrical energy, typically in the form of transient voltage spikes or surges. They help protect sensitive electronic devices from damage caused by these voltage fluctuations.

Protectors are devices that provide protection against various electrical disturbances, such as electromagnetic interference (EMI) and radio frequency interference (RFI). They are commonly used in electronic systems to ensure proper functioning and prevent interference from external sources.

In summary, NATO Supply Class 5920 includes fuses, arrestors, absorbers, and protectors, which are essential components in electrical and electronic systems. They provide protection against overcurrent, overvoltage, and other electrical disturbances, ensuring the safe and reliable operation of equipment.
