Abstract
An electromagnetic circuit breaker is provided with a pair of magnets on opposing sides of the contacts in the open position. A magnetic field generated by the magnets combines with the magnetic field generated by the electrical arc created upon opening of the contacts during an overcurrent condition sensed by the breaker. The combined magnetic fields deflect the arc current, shifting the arc current away from the contact points and lengthening the path of the arc, thereby increasing the voltage rating of the breaker, by decreasing the intensity of an associated arc current.
