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 |

Circuit breaker with overload, short circuit and under voltage protection device to protect the power lines and equipment from damage.
The circuit breaker can be installed vertically (ie, vertical loading), or horizontally (ie, cross-loaded).
Rated insulation voltage 800V,suitable for AC 50HZ, rated working voltage 690V and below the circuit for infrequent start with.
