A circuit breaker is provided having an operating mechanism for rotating a blade about a pin between an OPEN position and a CLOSED position, thereby separating and engaging a stationary contact and a movable contact which is secured to the blade. The operating mechanism has a frame and a first link coupled at one end thereof to the frame and its opposite end coupled to a first end of a second link. The operating mechanism further includes a third link having a first end coupled to a second end of the second link and a second end coupled to the blade for moving the blade between the OPEN position and the CLOSED position. The first and second links are disposed on the opposite side of the pin from the movable contact.
