● It is applicable to power conversion, distribution and control of power plants, substations, industrial and mining enterprises, petrochemical, metallurgy, high-rise buildings, hospitals, expressways, municipal engineering, and other projects where the electrical system is used as power supply, power distribution, and motor centers.

● The device is a new type of low-voltage distribution cabinet featured with safety, economy, rationality and high reliability. It has the characteristics of convenient and flexible combination of electrical schemes, stable series, strong practicability, high protection grade, and long service life.

● The device is a new type of low-voltage distribution cabinet featured with safety, economy, rationality, and high reliability. It has the characteristics of convenient, flexible, andstable combination of electrical schemes, strong practicability, high protection level, and long service life.

● Unattended running is realized with functions of remote control, telemetry, remote adjustment, and remote signaling, etc.

Normal service conditions:

● The ambient air temperature shall not exceed + 40℃, and the average temperature within 24h shall not exceed + 35℃.

● Atmospheric conditions: the air is clean. When the maximum temperature is +40 ℃, the relative humidity shall not exceed 50%. Higher relative humidity is allowed at lower temperatures. For example, 90% if 20℃. However, it should be considered that moderate condensation may occur occasionally due to temperature changes.

● The lower limit of ambient air temperature is - 5℃

● The altitude shall not exceed 2000m.

● Inclination to the heavy straight surface shall not exceed 5 degree when installing the equipment.

● Pollution level 3: there is conductive pollution or dry non-conductive pollution becomes conductive pollution due to condensation.

● The equipment shall be installed at a place free of violent vibration, impact, and strong corrosion which might impair the electrical components.

★ Please consult to reach an agreement for the special use conditions that exceed the normal use conditions.
