Claims
- 1. A device for limiting electric current in a current interruption device, comprising:
- two stationary contacts including terminal means and a bridging contact movable toward and away from a position bridging said stationary contacts;
- a conductor connected to each of said stationary contacts;
- said bridging contact moving away from said bridging position at a value of the current flowing through said conductors such that upon interruption of the current therethrough the voltage across said stationary contacts is sufficient to generate an arc therebetween, said arc traveling along said conductors away from said stationary contacts by the magnetic field generated from the current flowing through said conductors; and
- means interconnecting the ends of said conductors remote from said stationary contacts to provide a parallel current path for said arc, and including means for interrupting said current from the terminal means to said arc.
- 2. Device accordance with claim 1 wherein said end member is a stationary through-connection.
- 3. Device in accordance with claim 1 wherein said end member is an interrupter.
- 4. Device in accordance with claim 3, wherein said interrupter is an electrical switch.
- 5. Device in accordance with claim 3, wherein said interrupter is an electrical safety fuse.
- 6. A device for limiting electric current in a current interruption device, comprising:
- two stationary contacts including terminal means and a bridging contact movable toward and away from a position bridging said stationary contacts;
- a conductor connected to each of said stationary contacts;
- said bridging contact moving away from said bridging position at a value of the current flowing through said conductors such that upon interruption of the current therethrough the voltage across said stationary contacts is sufficient to generate an arc therebetween, said arc traveling along said conductors away from said stationary contacts by the magnetic field generated from the current flowing through said conductors; and
- means interconnecting the ends of said conductors remote from said stationary contacts to provide a parallel current path other than that for said arc, and including means for interrupting said current flowing through said conductors.
