For short circuit protection, it can also be used for infrequent on/off operation and conversion of lines. The interior adopts a bipolar structure design, in which one pole is protected, and one pole is unprotected and the bipolar structure simultaneously closed and disconnected, thereby solving the hidden danger of using only one pole switch at the single-phase end of the residential house.
