A circuit breaker is an essential safety device in electrical systems that automatically interrupts the flow of electricity to prevent damage from overloads or short circuits, acting as a reusable alternative to fuses. In modern usage, the term also applies to financial mechanisms that temporarily halt trading on stock exchanges during extreme volatility to avoid market crashes and protect investors. This dual role highlights its evolution from pure engineering to a metaphor for stability in high-stakes environments.
