Rövidzárlatkikapcsolás

Rövidzárlatkikapcsolás is a Hungarian term that translates to "short-circuit shutdown" or "short-circuit interruption." It refers to the automatic disconnection of an electrical circuit when a short circuit occurs. A short circuit is an abnormal connection between two points in an electrical circuit that have a different electrical potential, usually between the live wire and the neutral wire, or between the live wire and ground. This unintended low-resistance path allows a large amount of current to flow, which can cause overheating, fire, and damage to equipment.

The primary purpose of short-circuit interruption is to protect electrical systems and users from the hazardous effects of a short circuit. This is achieved through protective devices such as circuit breakers and fuses. When a short circuit causes the current to exceed a predetermined safe limit, these devices rapidly interrupt the flow of electricity. Circuit breakers are resettable, meaning they can be manually or automatically reset after the fault has been cleared. Fuses, on the other hand, are single-use devices that melt and break the circuit when the excessive current flows through them, requiring replacement after activation.

Effective short-circuit interruption is crucial for electrical safety and the reliable operation of any electrical installation. It prevents catastrophic failures, reduces the risk of electric shock, and minimizes damage to appliances and wiring. The speed and sensitivity of the protective devices are important factors in minimizing the duration and impact of a short circuit.
