What is the function of a circuit breaker in an electrical installation protection system?

In the broadly understood category of switches, you can find, among others, light switches and switches, cross switches, bell buttons or candlestick switches. However, these are elements of lighting systems, while in the product subcategory we are discussing, we present devices that protect the electrical installation in a situation where the current exceeds the safe value for a given circuit. The disconnector and overcurrent circuit breaker, because they are the ones we are talking about, are functional electrical devices that are used in installations in every home.

Their basic task is to cut off power when there are irregularities in the power supply in the electrical installation - including overloads and short circuits. They are also able to turn on or off the current in normal operating conditions of the circuit. Power switches are also used to control and protect the receiving circuits of electrical installations and devices against the harmful effects of overload and short circuit currents.
