    摘要： The electrical motor protector includes a housing being constructed of an electrical conductive material and having a first electrical contact disposed therein. Within the housing, a movable cantilever assembly is disposed and carries a second electrical contact thereon. Upon malfunction or overheating of the motor, the motor protector will break electrical connection between the first and second contacts to thereby interrupt electrical current to the motor, to render the motor inoperative.The cantilever assembly will be responsive to temperature wherein overheating of the motor will act to break the electrical connection between the first and second contacts, after which the motor will have a chance to cool before electrical connection is remade. The cantilever assembly includes first and second cantilevers which act in conjunction with one another to increase the cycle time of the device as well as providing a variety of other benefits and advantages.
