    • PROBLEM TO BE SOLVED: To provide a method for detecting electrical arc failures that have a reduced sensitivity about nuisance tripping. SOLUTION: A device includes a current sensor, an input sensing circuit, an arc discharge sensing circuit, power supply, a tripping circuit, a processing unit, and an electromechanical interface. The processing unit measures a plurality of voltage levels supplied by the arc discharge sensing circuit during a particular number of continuous time periods. Next, the processing unit determines the number of continuous time periods when a voltage level exceeds a particular minimum value, or takes continuously lower value or higher value, alternatively falls out of range of a predetermined usual value. Based on the result of this determination, the processing unit shuts off electric power to loads by tripping an electromechanical interface, or prohibits the electromechanical interface to reduce the occurrence of nuisance tripping.

The ASIC also includes diagnostic test bridges BR1 and BR2 for diagnosing ASIC faults and a signal diagnostic path 10m for diagnosing sense element and sense element connection faults. Characteristic data downloaded to the host controller enables the controller to mathematically correct temperature, condition, and diagnostic signal errors.

      SOLUTION: This range determination device is provided with: polarity sensors 26 (26a-26c); first magnets 24 relatively movably arranged with respect to the polarity sensors 26 in response to selection of the range of an automatic transmission, wherein polarity thereof is reversed at least at one position in the relative movement direction; a range determination means determining the range based on a detection signal of the polarity of the first magnet 24 detected by the polarity sensor 24 in response to the relative movement; and magnetic bodies 25 each arranged at a position increasing magnetic flux density in the vicinity of the boundary of the first magnet with the polarity reversed in the relative movement direction.
