Low voltage electrical switchboard for electric energy input with an automatic switchover implemented on the contactors of YuU (ShU)-El-8200 series

Description

Low voltage electrical switchboards of YaU (ShU)-El-820 series are designed for equipping of electric energy input and distribution boards with an automatic transfer switch. Low voltage electrical switchboard of YaU (ShU)-El-820 series provides automatic switching of lighting and power equipment to stand-by power supply when normal supply voltage in AC networks disappeared. Consumers are switched over to the normal power supply automatically when the normal supply voltage is restored. Continuous-time service

Low voltage electrical switchboard of YaU (ShU)-El-820 is manufactured in accordance with GOST R 51321.1-2007 and TS-3434-002-50617349-2015.

Low voltage electrical switchboard of YaU (ShU)-El-820 provides performance of the following functions:

  • continuous monitoring of voltage in the main and emergency power source circuits;
  • provision of automatic restoration of the normal power supply of electric energy consumers by connecting an emergency power source with the preset delay time (0,1…10 s);
  • provision of automatic recovery to the emergency power supply circuit of consumer’s electrical installations after the restoration of the main power supply source with the preset delay time delay (0.1…10 seconds);
  • protection of a bow collector against short circuit and overload.
