Overview

1. Installation category

Class IV for main circuits of the circuit breaker and voltage tripper coil and primary coil of power transformer; Class III for auxiliary circuit and control circuits. The inclination with the vertical plane does not exceed 5° when installation.

2. Pollution class: 3

3. Altitude ≤2,000m, derating when above 2,000 m.

4. Atmospheric conditions

The relative humidity does not exceed 50% at the ambient temperature of +40°C, and a higher relative humidity at the lower temperature may be allowed;

The relative humidity at the low temperature +25°C can be up to 90%. The necessary measures can be taken for condensation on the product surface due to temperature changes.

5. Protection level IP20 for the front and IP00 for the remaining

6. Electromagnetic interference Suitable for electromagnetic environment
