Such a device is simply essential in any electrical panel, next to the meter. Even simple able to save not only life, but also property. So why do we need these difavtomats, whose function is only to turn off the current.
Difavtoat or RCD. Similarity and difference
Those who are not connected to electricity do not see much difference. After all, their destinations are very similar. Meanwhile, you need to understand such a thing.
A special transformer is located in the RCD, and when a current leak occurs, the electromagnetic field of the coil is violated, the rod presses the lever and turns off the current.
But the differential machine has more features. It will also protect the network in case of leakage, but the presence of a built-in circuit breaker inside allows you to protect the network from short circuits and overloads. The combination of two functions makes it more cost-effective. Long voltage surges above 365 V are no longer terrible, the machine will instantly work.
Several characteristics
A circuit breaker integrated in the difavtomat works together with a differential protection module. By this they provide power to an electronic amplifier, which has a sensor. In case of leakage or overload, the differential transformer transmits a signal to the amplifier, which includes a reset electromagnet coil.
Constantly directed magnetic fluxes are created inside the machine. If they are violated, when, for example, suddenly the body touches the voltage wire, the flow is disturbed and the electromagnet shifts the latch of the switch mechanism.
The advantages of a circuit breaker are that it operates very quickly. The slightest overload or short circuit leads to an immediate shutdown. At the same time, the machine itself can operate at temperatures from -25 to + 50 degrees. It is impossible not to say about a high degree of reliability and a long service life.
Installation of circuit breakers
When experienced professionals advise you to buy and install several circuit breakers at once, then you need to listen to this.
This will help in the future not only to prevent an accident, but also protect electrical appliances from a sudden power surge or short circuit.
Even in an ordinary apartment, instead of one RCD, it is better to put several circuit breakers. Especially if the wiring was installed long ago and, moreover, aluminum.
New appliances that have now appeared in every home are not designed for such wiring. They are more powerful than those that were made 20-30 years ago. Therefore, the likelihood of a circuit. But that is not all. One burned-out appliance can damage everyone else.
Therefore, it is necessary not only to change all the old wiring, but also to try for an alarm, a washing machine, a computer, kitchen units, lighting in the rooms to make an independent wiring and connect a circuit breaker to each wire.
This will not only protect the apartment, but also help to easily find the cause of the problems and eliminate them. In this case, it will not be necessary to turn off the rest of the light and appliances.
