The main criteria for choosing a circuit breaker

An automatic circuit breaker is an equipment necessary to protect wiring and electrical appliances from overloads and short circuits that may occur in an electrical network. In the event of an emergency, an overcurrent may well flow to the home electrical wiring, which can lead to damage to household appliances and even to melting of the cable insulation.This situation significantly increases the risk of fire. That is why circuit breakers are currently being installed, which quickly disconnect the wiring in the house from the supply of electricity from the city grid in the event of power surges. When choosing a circuit breaker, it is necessary to pay attention to certain parameters.What to pay attention to when choosing a circuit breaker is the short circuit current. When purchasing a circuit breaker, it is worth remembering that the PUE regulations currently prohibit the installation of appropriate equipment, the most disabling capacity of which is less than 6 kA. Modern switches can have parameters such as 3, 4.5, 6 and 10 kA. If a private house is located near a substation, then you should buy a switch that is able to react correctly in case of a short circuit of 10 kA. In other cases, you can do without a switch with a nominal value of 6000 A. This is the operating (nominal) current. After the previous criterion, when choosing a circuit breaker, the rated current parameter comes in second place. This indicator shows the value of the current, when exceeded, the machine will forcibly break the circuits, protecting the wiring from overload. To choose the right switch according to the nominal value, first of all, the cable cross-section that the home wiring has should be taken into account. It is also worth taking into account the power consumption of household appliances.- The actuation current. Along with the rated current, its operating current should be taken into account when choosing an automaton. As you know, when switching on sufficiently powerful household appliances, the inrush current can be much higher than the operating current. It is for this reason that you should choose the right class of circuit breaker so that it does not work when electrical appliances are turned on, mistaking the inrush current for a short circuit.
