Protecting the wire harness from over-temperature damage is crucial to prevent potential serious injuries and severe damage to the car, its passengers and its surrounding. Traditional melting fuses and relays were sufficient in the past and present architectures, but they are no longer adequate for the increasing functionalities, safety requirements, and the evolution of automotive power distribution into zone architectures. The advancements in the automotive industry, such as software-defined vehicles, green mobility, and automated driving, demand more functionalities that require dependable power supply. Furthermore, the growing number of functional-safety requirements has made wire protection increasingly critical.
