Abstract

Official abstract text for this publication.

An arc runner assembly for use in a circuit interrupter provides a pair of arc runners that are situated at opposite sides of a stationary contact of the circuit interrupter. If used in a DC application, the arc runner assembly is configured to communicate a positive DC arc along one of the arc runners in a first direction away from the stationary contact and is further configured to communicate a negative DC arc along the other arc runner in another direction away from the stationary contact. The arc runner assembly additionally includes a support that is electrically engaged with a conductor of the circuit interrupter on a surface opposite that on which the stationary contact is disposed. The improved arc runner assembly advantageously facilitates extinction of electrical arc and extinguishes both positive and negative DC arcs in a DC application.

First claim

Opening claim text (preview).

What is claimed is: 1. An arc runner assembly structured for use in a circuit interrupter having a first conductor, a second conductor, a set of separable contacts electrically interposed between the first conductor and the second conductor, and a magnet apparatus that is structured to generate a magnetic field, the set of separable contacts comprising a stationary contact situated on one of the first conductor and the second conductor, the arc runner assembly comprising: a first…
