Abstract
A circuit breaker having an arc chute adjacent the arc path between a fixed and a movable contact. To aid in extinguishing the arc under short circuit conditions, an arc suppressor element is fixed on a movable surface adjacent the movable contact; and preferably on the arm itself facing the fixed contact and arc chute. The arc suppressor is made from a thermoplastic material such as nylon 6/6 which has high temperature resistance and high dissipation factor, and absorbs a relatively large amount of water. During interruption of a high current arc, heat shock liberates gases and water vapor from the suppressor material to neutralize arc ions and blow the arc toward the chute.
