Abstract: The present invention provides a unique circuit breaker that can fit inside restricted spaces and even existing hardware that would otherwise be inaccessible with current circuit breakers. In at least one embodiment, the present disclosure provides a circular circuit breaker with an opening through which wires, hardware, and other equipment can be inserted. The circular circuit breaker departs from generally accepted engineering criteria and enables the use of circuit breakers in far greater numbers of existing electrical devices, such as fans, lamps, and other restricted area electrical devices. The circular circuit breaker can include various electrical devices to enable its function, and the extension of one or more leads therefrom. In at least one embodiment, the circuit breaker can be automatically resettable. When the rated wattage is exceeded, the circuit breaker is tripped and after the wattage is reduced, the circuit breaker automatically switches to an on-state.
