The application scope of the leakage protector is as follows: Mobile electrical appliances with no double insulation and rated working voltage above 110V, Construction sites, Temporary line, Home appliances.

The leakage protector is used to effectively protect the direct and indirect contact of the low-voltage power grid, and it can also be used as the phase loss protection of the three-phase motor. It has single-phase and three-phase.

Iron-based amorphous ribbon is an ultra-fine grain structure that can replace silicon steel, permalloy, ferrite and other materials.

In order to eliminate the interference signal input on the signal line and various induced interference, the manufacturer must reasonably arrange the filter circuit to filter the interference of common mode and series mode. The common mode inductor is an integral part of the filter circuit. The common mode inductor is essentially a two-way filter: on the one hand, it needs to filter out the common mode electromagnetic interference on the signal line, and on the other hand, it must suppress itself from emitting electromagnetic interference, so as to avoid affecting the normal operation of other electronic devices in the same electromagnetic environment. 

Common mode choke coils are often used in computer switching power supplies to filter common mode electromagnetic interference signals. The common mode inductor is essentially a two-way filter. In the design of the circuit board, the common mode inductor also plays the role of EMI filtering, which is used to suppress the electromagnetic waves radiated by the high-speed signal lines.

Nanocrystalline core is a key component for the stable operation of electronic power equipment. It can precisely detect the current size, and can also filter the clutter in the circuit to ensure the stable transmission of communication signals.
