The SZE3/SGP System Switchgears are designed for distribution of electricity, as well as for control and protection of electrical equipment against short circuits and overloads. They give the user a high level of safety and comfort. The main features of SZE-3 switchgears are modularity and compactness. Also, the cabinets are adapted to the units they hold so that the units can be used fully.
