PROCESSOR CONTROLLED CIRCUIT BREAKER TRIP SYSTEM HAVING AN INTELLIGENT RATING PLUG |
摘要 |
A rating plug circuit is used in a processor-based circuit breaker tripping system having a current sensor for sensing current from a current path. The rating plug circuit includes a printed circuit board and a resistor that is connected to the printed circuit board for establishing a designated voltage in the presence of a predetermined amount of sensed current. A connector having a plurality of conductive contact points, interconnects the printed circuit board with the tripping system, and a plurality of printed circuit paths are included on the printed circuit board to provide a binary code at the contact points. The binary code indicates the value of the resistor and is read by the processor to analyze the current in the current path.
