Product Introduction
The X-21 power distribution cabinet is suitable for power users in metallurgy, mining, petroleum, chemical industry, electric power, light and textile industries, building materials, mechanical processing, transportation, hotels, and restaurants—covering applications involving AC power at 50 (60) Hz with a rated operating voltage of 380 (400) V, including power supply, motor control, and lighting.
Model Meaning
Operating environment
▷ The ambient air temperature shall not exceed +40℃, nor fall below -25℃, and its average temperature over a 24-hour period shall not exceed +35℃.
▷ No explosive gases, corrosive gases, or conductive dust;
▷ The relative humidity shall not exceed 50% when the maximum temperature is +40℃; at higher temperatures, a higher relative humidity is permissible—for example, 90% at +20℃.
▷ Altitude not exceeding 2000m;
▷ The temperature during transportation and storage can range from -25℃ to +55℃, and for short periods (no more than 24 hours), it should not exceed +70℃.
