Contact Configuration System For Circuit Breakers

Abstract: The various embodiments of the present invention provide a contact configuration arrangement in the circuit breaker to provide the compensation forces to cancel the constriction forces formed at a contact strip during high short circuit currents. The arrangement comprises a contact strip brazed to the vertical arm connected to a first flexible conductor connected to a first stationary conductor and a pin integrated to a movable conductor connecting a second stationary conductor with a second flexible conductor. The first stationary conductor, the first flexible conductor and the vertical arm forms a current carrying path loop to provide the compensation forces to cancel the constriction forces during short circuit conditions.
