<p>A circuit breaker (10) having a movable upper blade (16) with a free floating pivot end (46). The operating mechanism (34) is solidly connected to the upper blade (16). The contact force is generated by a contact spring (44) which exerts an upward force on the lower blade (26). As the contacts (18, 22) separate, the force exerted on the upper blade (16) is virtually eliminated, reducing substantially the resistance at the pivot end (46) of the upper blade (16). The load terminal (12) and pivot end (46) of the upper blade (16) provide a current path parallel to that of the load side flexible connector (15).</p> |
