Abstract
A circuit breaker consisting of a housing having a fixed contact and a movable contact mounted on a blade which in turn is pivotally supported on a blade carrier that is pivoted within the housing and a handle that cooperates with the blade carrier to pivot the carrier between positions. A trip lever is pivotally mounted in the housing and has biasing means interposed between the blade and the trip lever to pivot the blade between respective positions with latch means holding the trip lever in a position where the blade and blade carrier are biased to close the contacts. The handle and carrier have cooperating camming surfaces that magnify the forces applied to the handle for pivotal movement of the carrier.
