Type Designation Operating Conditions 1. Ambient temperature: -5℃~+40℃; 2. Air conditions: At mounting site, relative humidity not exceed 50% at the maximum temperature of +40℃. For the wettest month, the maximum relative humidity averaged shall be 90% while the lowest temperature averaged in that month is +20℃,special measures should be taken to occurrence of condensation. 3. Altitude: ≤2000m; 4. Pollution grade: 2 5. Mounting category: III; 6. Mounting conditions: i...

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...
