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.
