I  Use and characteristics

LGGD AC low-voltage distribution cabinet for power plants, substations, industrial enterprises and other power users as AC 50Hz, rated voltage 380V, rated current up to 3150A in the distribution system, as power, lighting and power distribution equipment conversion, distribution and control purposes.

LGGD AC low-voltage distribution cabinet is in a safe, economic, rational and reliable design of the new principle of low-voltage distribution cabinet. Products with high breaking capacity, dynamic thermal stability, electrical program flexible combination of convenience, the series of, practical, high degree of protection features.

LGGD low voltage distribution cabinet meet IEC439 "Low-voltage switchgear and control equipment", GB7251 "Low-voltage switch equipment" and other standards.

II  Environmental conditions

♦ The ambient air temperature is not higher than +40 ℃, not less than -5 ℃. 24h no larger than the average temperature of +35 ℃.

♦ indoor installation, the use of site altitude does not exceed 2000m.

♦ The maximum relative humidity in the ambient air temperature of +40 ℃not more than 50%. At low temperature allows the greater the relative humidity (for example: 20 ℃90% when) should take into account the changes due to temperature may be an accident, the impact of condensation.

♦ When installing the unit and the vertical gradient of no more than 5 degrees.

♦ The device should be installed in the absence of severe vibration and shock, and electrical components from corrosion less than the place.

♦ If the user special requirements, please consult our company.
