Panels SHO-70

Distribution panels of the ЩО series boards are designed to receive and distribute three-phase alternating current with a frequency of 50 Hz and a voltage of 380/220 V, protect against overloads and short-circuit currents, and are used to complete switchgear with a solidly earthed neutral. Enclosure protection rating according to GOST 14254: IP20 from the facade side; IP00 from other sides. The panels are designed for one-sided maintenance. The panels are designed for operation in moderate climate conditions, placement category 3 according to GOST 15150, the lower limit of the ambient air temperature is minus 50 °C. They are installed in electrical rooms: altitude above sea level no more than 2000 m; non-explosive environment, not containing conductive dust, as well as aggressive vapors and gases in concentrations that cause destruction of metal and insulation; relative air humidity 90% at a temperature of 20 °C. The working position in space is vertical with an acceptable deviation of no more than 50 degrees in any direction. The nominal operating mode is continuous. The type of maintenance is periodic.
