Abstract
An integral electrical circuit controller apparatus selectively connects a load to a power source and includes an electrical contactor having contacts, a circuit breaker having separable contacts connected in series with the electrical contactor and a trip mechanism responsive to current flowing through the separable contacts for tripping the contacts open in response to predetermined current conditions, and a current throttle impedance for limiting short circuit current. The trip mechanism and the electrical contactor independently interrupt current flowing through the electrical contactor and the circuit breaker. The current throttle impedance limits short circuit current flowing through the electrical contactor and the circuit breaker until current is interrupted. The electrical contactor may include an overload relay. The current throttle may include a coiled conductor of nichrome or iron wire enclosed in a dielectric housing. The coiled conductor may have a generally cylindrical shape and may be user-modifiable.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
