Abstract:
A circuit breaker, comprising:a) a first, second, third and fourth pole, each of said poles having a circuit interruption mechanism said circuit interruption mechanism of said first, second, third and fourth poles being manipulated from an open position to a closed position by an elongated member that passes though an opening in an actuation member of each of said circuit interruption mechanisms of said first, second, third and fourth poles, said second pole being positioned intermediate to said first pole and said third pole, said third pole being positioned intermediate to said second and said fourth pole;b) a single operating mechanism for applying a force to said elongated member, said operating mechanism applying a force to said elongated member at a first position and a second position, said first position being intermediate said first and second poles and said second position being intermediate said third and fourth poles, wherein said single operating mechanism comprises:i) a pair of sidewalls each having an inner and outer surface, one of said pair of sidewalls being positioned at said first position and the other being positioned at said second position;ii) a handle yoke being pivotally mounted to said pair of sidewalls for movement between a first position and a second position on said outer surface of said pair of sidewalls;iii) a pair of engagement arms one of said engagement arms being mounted for movement on one of said outer walls and the other being mounted for movement on the outer surface of the other side wall; andiv) a pair of linkage mechanisms being coupled to said handle yoke at one end and said pair of engagement arms at the other, said pair of linkage mechanisms being configured, dimensioned and positioned to manipulate said pair of engagement arms from an open circuit position to a closed circuit position as said handle yoke is moved from said first position to said second position, said closed circuit position causing said elongated member to close said circuit interruption mechanism of said first, second, third and fourth poles.
