Abstract
A direct mount rotary handle operating mechanism for operating a circuit breaker having electrical contacts. The handle mechanism includes a driver coupled to the circuit breaker and a handle having a socket for receiving the driver. The socket is configured to allow the handle to rotate relative to the driver. The handle further includes a movable locking pin. A lock latch is associated with the driver, wherein the lock latch includes a flange portion. When the electrical contacts of the circuit breaker are welded closed and a torque is applied to the handle, the handle rotates to a position in which the pin is blocked from being inserted into the locking hole by the flange portion thereby preventing the handle from being locked in an OFF position when the contacts are welded together.
