Abstract
A molded case circuit breaker enclosed in a metal cabinet with an openable cover. An operating mechanism has a mounting plate secured to the face of the circuit breaker and a sliding plate movably supported on rollers by the mounting plate at the side of the circuit breaker. A handle mechanism is secured to the sliding plate with a portion extending through an aperture in the cabinet cover. A gasket is disposed between the handle mechanism and the interior of the cabinet cover. The handle mechanism is spring-loaded against the gasket and interior of the cabinet cover to provide a dust-tight seal.
