FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to devices for sectioning power lines, and is intended for switching, protecting the electrical network, electricity metering, monitoring the quality of electricity, monitoring the amount and time of voltage outages in distribution networks of three-phase current, automation of electrical networks. Technical results are achieved due to the fact that the multi-contact switching system, which has independent control of two power contact groups with redundant power circuits, consists of an input switching element for manual control, the first switching element for remote control, the second switching element for remote control, the first output switching element for manual control, the second output switching element of manual control, a control unit of the first switching element of remote control, a control unit of the second switching element of remote control, a control unit of multi-contact switching system, a unit of receiving and transmitting data, an uninterruptible power supply unit, the first changeover switching element of manual control, the second changeover switching element manual control, the first and second circuit breakers.
EFFECT: expanding the functionality and scope of its use as well as increasing the reliability and efficiency of consumer power supply systems.
