    Normal working conditions




    1. The upper limit of ambient air temperature shall not exceed +70°C, the lower limit shall not be lower than -25°C, and the average-value VI within 24 hours shall not exceed +35°C.

    2. The altitude of the installation location shall not exceed 2,000 m.

    3. The relative atmospheric humidity does not exceed 50% when the ambient air temperature is +40°C, and a higher relative humidity is allowed at a lower temperature. The average maximum relative humidity in the wettest month is 90%, and the average maximum temperature in this month is +25°C. Measures shall be taken to deal with the occasional condensation due to temperature changes.

    4. Contamination grade: Grade 3.

    5. Protection degree: IP20.

    6. The installation category: Grade II and III.

    7. Install this MCB with TH35-7.5 standard rail.

    8. The magnetic field near the installation site shall not exceed 5 times of the geomagnetic field in any direction.

    9. This MCB shall generally be installed vertically, and when the handle is upward, the power is on. The installation place shall have no significant shaking and impact vibration.
