Operation and installation condition 1. Ambient air temperature:-5℃~+40℃， average temperature of 24 hours must below +35℃ 2. Altitude:≤2000m 3. Relative humidity: The maximum temperature of 40 degrees,the air relative humidity not exceed 50%,at a lower temperature can allow for a higher relative humidity.The humidest month’s average lowest temperature must be below 25℃,  the max relative humidity of that month should not exceed 90%.If humidity changes as a result of occasional gel generated,...

Feature Feature 1: Current limiting ability Limiting the rise of short circuit current of circuit. The peak short circuit current and I2t power are much lower than the value expected. U shape fixed contact design The U shape fixed contact design achieves the technique of pre-breaking: When the short circuit current pass through the contact system, there are forces that repel each other on the fixed contact and moving contact. The forces were produced with short circuit current synchronous and...
