General:
| Feature Limiting the rise of short circuit current of circuit. The peak short circuit current and I2t power are much lower than the value expected. Feature 1: Current limiting ability 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 enlarge while short circuit current enlarge. The forces make the fixed contact and moving contact apart before tripping. They elongated the electric arcing to enlarge their equivalent resistance to limit the rise of short circuit current. |
