Abstract
An extension handle assembly includes: a housing; a handle driving the knob to rotate from a first position to a second position during a manual tripping period of a motor protection circuit breaker and drives the handle to rotate from the first position to a third position during a fault tripping; a stopper configured to abut against the handle upon the handle rotating from the first position to the second position during the manual tripping period, to provide a stopping force for a rotation of the handle to increase a force required for the rotation of the handle from the first position to the second position; and configured not to abut against the handle upon the handle rotating from the first position to the third position during the fault tripping period, not to provide a stopping force for the rotation of the handle.
