AISIKAI MCCB Normal working conditions and installation methods |
|
| Category | Requirements |
| Elevation | Installation site not exceeding 2000 meters above sea level |
| Ambient air temperature | The upper limit does not exceed+ 40 ºC; the lower limit does not exceed - 5 ºC; the average value of 24 hours does not exceed + 35 ºC |
| Pollution Level | Level 3 |
| Installation Category | Installation Category Ill, Circuit Breaker 1600A IV |
| Atmospheric conditions |
Atmospheric relative humidity does not exceed 50% when the ambient air temperature is + 40 C. It can have a higher relative humidity at a lower temperature. The average maximum relative humidity of the wettest month is 90%, and the average minimum temperature of the month is + 25 C. Considering the condensation occurring on the surface of the product due to temperature changes. |
| Installation Conditions |
Installed in places without significant shaking and shock vibration, the magnetic field near the installation site should not exceed 5 limes of the magnetic field in any direction, and leakage circuit breakers should generally be installed vertically. |
| Installation | Circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally). |
| Input mode | Circuit breaker can't go down, that is, only 1,3,5 power lines, 2,4,6 load lines |
