Abstract
A circuit interrupter has a first contact, a second contact movable with respect to the first contact, an arcing chamber, and an arc splitter. The arc splitter is located on a first side of the first contact, as is an arc runner. An electrical conductor is connected to the arc runner having a first portion running from the first side of the first contact towards a second side of the first contact, the second side being opposite the first side with respect to the first contact. A second portion is connected to the first portion and the second contact; the second portion is located on the second side of the first contact. A current running through the arc runner and the electrical conductor generates a magnetic force on the arc moving the arc toward the arc splitter.
