The leakage protection switch is a switching element that actively determines whether leakage or insulation damage occurs in the main circuit and turns it on or off. The most common situation is that electricity overload, leakage, short circuit and other phenomena occur in the home. Today we will talk about the principle of leakage protection switches and the introduction of leakage protection switch brands.

Principle of leakage protection switch

There are two groups on an iron core: an input current winding and an output current winding. When there is no leakage, the input current and output current are equal. If the vector sum of the two magnetic fluxes on the iron core is zero, no potential will be induced on the third winding. Otherwise, a voltage will be induced on the third winding, which will be amplified to push the actuator and cause the switch to trip.
