ABSTRACT OF THE DISCLOSURE A retractable handle mechanism for controlling the operating handle of a circuit breaker. The handle mechan- ism consists of a housing which may be mounted on an electrical enclosure in which the circuit breaker may be disposed. Pivotally attached to the housing is a first lever which is movable between an on position and an off position. Retractably attached to the first lever is a second lever which is movable between a first position substantially adjacent the first lever and a second posi- tion substantially extended away from the first lever. The retractable handle mechanism may also be equipped with a lever locking mechanism which allows the second lever to be non-movably disposed in either its first position or its second position. The retractable handle mechanism may also be equipped with a lever off locking mechanism which prevents the first lever from being moved from the off position to the on position.
