Überstromschutz refers to overcurrent protection, a safety mechanism used in electrical systems to prevent excessive current flow. This protection is crucial for safeguarding electrical devices and wiring from damage caused by overloads or short circuits. The primary components of Überstromschutz include fuses and circuit breakers. Fuses melt when the current exceeds a certain level, breaking the circuit, while circuit breakers can be reset after tripping. Both devices help ensure the safety and reliability of electrical installations by interrupting the flow of electricity when necessary.
