ABSTRACT:
A circuit breaker having a contact assembly with a double pivot arrangement. The moving arcing and main contacts provide a smooth surface for meeting the lower arcing contact and the lower main contacts, each mounted on a separate semi-stationary lower blade. The lower arcing contact is positioned higher than the lower main contact, making the arcing contact the last to separate from the moving contact. An arc horn is mounted adjacent the moving contacts to provide a path for movement of the arc from the upper contact into the arc stack assembly. The arc horn has three fingers, each of which passes through the cutaway portion of each arc plate of the arc stack assembly upon the contacts separating.
