    Low voltage electrical switchboard for electric energy input with an automatic transfer switch of ShU-El-8700 series

    Description

    Low voltage electrical switchboards for electric energy input with an automatic transfer switch of ShU-El-8700 series are designed for automatic mutual change-over of the power of busbar sections of different low voltage power supply inputs. Schemes of an automatic transfer switch are developed based on microchip technology with the possibility to record events, parameters, and integration into the automated data management system of power supply according to the Modbus industrial Protocol. The data of Low voltage electrical switchboard are used to equip control station boards with incoming line sections with automatic transfer switches.

    Manufactured in accordance with GOST R 51321.1-2007 and TS-3434-002-50617349-2015.
