Abstract
A circuit interrupter having at least two sets of contacts that are electrically connected in series such that when the at least two sets of contacts are opened, they are opened simultaneously. This functions to increase the distance between the sets of contacts as the distance is additive for the series connected sets of contacts, which increases the arc voltage for breaking any arc that may form between the individual sets of contacts more effectively.
Claims16
A circuit interrupter comprising:
- a first set of contacts including a first contact and a second contact, movable into and out of contact with each other;
- a second set of contacts including a third contact and a fourth contact, movable into and out of contact with each other;
- said first set of contacts connected in series with said second sect of contacts;
- a contact arm carrier;
- a contact arm;
- wherein said second and said fourth contacts being positioned on said contact arm;
- wherein said first set of contacts are configured to open and close simultaneously with opening and closing of said second set of contacts;
- wherein a first plane defines movement of said contact arm carrier and said contact arm defines a second plane;
- and
- wherein the second plane is positioned at an angle other than perpendicular to the first plane both when the contacts are open and when the contacts are closed.
