China CJ19 Series Capacitor Changeover Contactors from Reliable Suppliers & Factory for Reactive Power Compensation
Type and meaning
Normal working conditions and installation conditions
- The ambient air temperature should not exceed +40℃, with the average temperature of no higher than +35℃ within 24 hours. The lower limit of the ambient air temperature should be -5℃. When the highest temperature is +40℃, the relative humidity of the air should not be higher than 50%; a higher relative humidity is allowed at a lower temperature.
- The altitude of the installation site should not exceed 2000m.
- Pollution level: level 3.
- Installation category: category II.
- Installation condition: the inclination between the installation surface of the contactor and the vertical plane should not exceed 5°.
- Impact and vibration: the product should be installed in a place without obvious shaking, impact and vibration.
