To provide rating and a function selected by minimum time and cost in an automation process by connecting an operating circuit and a circuit intermitting controller for controlling respective options via a corresponding exclusive resistor, and removing a resistor connected to a nonselected circuit.
A microprocessor is installed on a printed circuit board 34, and is provided with a resistor circuit for setting ampere rating of a circuit breaker and selecting other optional functions. Resistors 39 to 46 of the resistor circuit are arranged so as to form an arry, and are extended upward from the printed circuit board 34. The printed circuit board 34 is arranged on an upper surface of a transfer table 49 driven according to a command of a controller 52 by truing up the ends so that a resistor array becomes parallel to the advancing direction. A stepper motor 55 removes a prescribed resistor among the resistors 39 to 46 by a tool 54 of an end part of an arbor 53 operationally joined to the stepper motor 55 according to selected rating or function.
