Since our channel aims to answer all questions, we set out to explain this one further. The circuit breaker curve graph serves to map its operating characteristics in both overload and short-circuit. In short, this curve shows how long the circuit breaker can take to trip at a certain current. Circuit breakers with different curves (B, C or D) will have different tripping times and currents for both overload and short-circuit. The circuit breaker curve graphs help us identify the best type of circuit breaker for a given load. For example: A curve B circuit breaker will trip instantly when a current above 3x its nominal current runs through any of the poles. The same will not happen for the C-curve circuit breaker, which needs a current 5x above the nominal current. Since we are talking about circuit breakers, let's provide some technical data to make it easier to understand: They are devices that protect electrical circuits against the effects of short circuits and overloads. With this protection, you ensure greater safety for your electronic devices and, mainly, for you and your family. But what are circuit breakers made of: Lever: turns the circuit breaker on and off. Terminals: where the installation cables are connected. They must always be tightened to avoid poor contact. Trip accelerator: closes the circuit breaker contacts. It has a spring that makes it open quickly and can be activated by the lever or by one of the triggers. Thermal trigger: a plate composed of two metals. Called bimetal, it heats up when a current passes, generating a difference in expansion between the two metals and causing it to bend. In a normal situation, this effect does not act on the trip accelerator. Magnetic trigger: coil that, when traversed by an electric current, creates a magnetic field that attracts the trigger accelerator, disarming the circuit breaker. Do you have any questions?
