Cabinet NKU Moskovia (0.4 kV / up to 6300 A / 2b, 3b, 4b Sectioning)
(设备/材料)
描述:
NKU "Moskovia", type up to 6300A - low-voltage complete device, designed for reception and distribution of electric energy of three-phase alternating current with a frequency of 50 Hz and a voltage of 380/220 V in networks with a solidly earthed or isolated neutral, protection of electrical equipment from short-circuit currents and overloads, as well as for control, signaling, and measurement. NKU "Moskovia" is used as distribution devices on the low-voltage side (LVS) of complete transformer substations, as well as main distribution boards (MDB), SHSU, SHSN, SHR for currents up to 6300 A. NKU "Moskovia" is designed for indoor installation under the following environmental conditions: altitude above sea level - up to 1000 m; climatic version - U3.1 operating range of ambient temperatures - from minus 10 ° C to plus 40 ° C; average annual value of relative air humidity - no more than 75% at a temperature of plus 15°C; atmosphere type according to GOST 15150 - II; the environment is non-explosive, does not contain conductive dust, aggressive gases and vapors in concentrations that destroy materials and insulation.
