áramkörnél

Áramkörnél is a Hungarian term that translates to "circuit breaker" in English. It refers to an electrical safety device designed to protect an electrical circuit from damage caused by excess current. This excess current can result from an overload or a short circuit.

The primary function of an áramkörnél is to interrupt the flow of electricity when it exceeds a safe level, thereby preventing overheating of wires and potential fires. Modern áramkörnél units are typically thermal or electromagnetic, or a combination of both. Thermal types use the bending of a bimetallic strip to trigger the switch when it heats up from excessive current. Electromagnetic types use an electromagnet that pulls a lever to open the circuit when a large current flows through it.

When an áramkörnél trips, it opens the electrical circuit, stopping the flow of current. This requires the áramkörnél to be manually reset after the fault has been cleared. In residential and commercial buildings, áramkörnél are a standard safety feature, usually housed in an electrical panel or fuse box, often referred to as a "kapcsolótábla" in Hungarian. They are categorized by the amount of current they are designed to interrupt, with different ratings for different circuits. Understanding the function and importance of an áramkörnél is crucial for electrical safety.
