ABSTRACT:
The aircraft applicable current imbalance detection and circuit interrupter interrupts an electrical circuit when a current imbalance is sensed. The current imbalance detection and circuit interrupter includes a housing, power supplies, a sensor for sensing a current imbalance at the line side of the electrical circuit, a logic controller and a power controller. In a preferred embodiment, the invention can also include a fault indicator, a press to test switch and a reset switch. The power supplies provide power to the sensor, logic controller, and the power controller. The logic controller receives input from the sensor and the relay control signal, and the power controller receives input from the logic controller, and interrupts power to the load side of the electrical circuit when the sensor senses a current imbalance. Power interruption due to a sensed current imbalance is maintained until the line side power source is cycled. The circuit interrupter is preferably autonomous, requiring no additional signals, inputs, wiring or sources of power. The current imbalance detection and circuit interrupter is packaged in a configuration integral with the power controller, thus easing retrofit with the improved aircraft applicable current imbalance detection and circuit interrupter.
