ABSTRACT:
A motor has a shell formed to include an edge defining an opening that is either U-shaped or rectangular. A reversible apparatus has segments for mounting an overload protector having first and second body portions within the opening in the motor shell. The apparatus has a first profile for mounting the overload protector within a U-shaped opening in a motor shell so as to restrict movement of the mounting apparatus and overload protector assembly relative to the motor shell, and a second profile for mounting the overload protector within a rectangular opening in a motor shell so as to restrict movement of the mounting apparatus and overload protector assembly relative to the motor shell. The apparatus also includes a first part extending generally parallel to, and across a first surface of, the overload protector, a second part extending generally perpendicular to the first part and across a second surface of the overload protector, and a third part extending generally perpendicular to the second part and across a third surface of the overload protector so as to secure the protector to the mounting apparatus. In one embodiment, tenons formed on end portions of the mounting apparatus engage mortises formed in the protector. A snap-fit arrangement may also be provided. Flexible or crushable beads may be provided to reduce the ingress of contaminants.
