— the simplest kind of protective devices for single-phase networks. It has one screw terminal at the input and output. Such devices are used, in particular, to protect (individually) socket circuits and lighting circuits going into the apartment from the shield. Of the unambiguous advantages of single-pole models, compactness can be noted. In addition, switches for individual network segments can be installed at almost any distance from each other, and their characteristics can be different (for example, the operating current of the machine for sockets must be higher than for lighting).
