Circuit Breakers

The circuit breaker is selected based on the values ​​of the total leakage current and the rated current. The best electric machines are those in which the maximum switching capacity for devices in the group is 6 kA. The same indicator for terminal devices should be at least 3 kA.

Among the circuit breakers, it is worth paying attention to the models that protect against the breakage of the neutral wire. In the event of a break, the machine loses its supply voltage. In this case, the circuit breaker loses its working capacity.

Sensitivity of electric appliances

It is possible to provide excellent protection against the current that has gone out of control by mounting separate circuit breakers on each branch that consumes electrical energy and has excellent loads. To prevent a fire in the kitchen, where there is a cluster of electrical appliances with high power, electrical switches with low sensitivity are needed. Otherwise, the electric current will turn off each time the refrigerator is turned on. To protect the children’s room and bathroom, devices with maximum sensitivity will be required. These are circuit breakers that respond to a 10 mA current leak.
