Abstract
A hermetic motor protector ( ) has a non-current carrying snap-acting thermostatic disc ( ) freely disposed on a disc seat ( ) having a tab ( ) projecting through a centrally located aperture ( ) in the disc. An outer peripheral portion of the disc is received under a leg ( ) of the bracket limiting upward motion of the disc at that location and causing the disc to act as a lever pivoting about the disc seat ( ) as a fulcrum so that the outer peripheral portion of the disc diametrically opposite to leg ( ) engages a motion transfer bump ( ) formed on a movable contact arm cantilever mounted on leg ( ) when the disc snaps from its normally contacts engaged configuration to its opposite dished contacts open configuration when the disc is heated to its actuation temperature by a heater element ( ) along with heat conducted from a motor with which the protector is used.
