摘要： PURPOSE:To smooth the opening and closing operation of an operating handle and also to facilitate incorporation of a cradle, a reversing spring and the like by providing a rotation supporter only on the one side in the direction of the width of the operating handle and at the same time providing a projection in a cover. CONSTITUTION:An operating handle 3 which rotatably holds the base end of a movable contact element 30 capable of being brought into contact with and released from a stationary contact element 9 is pivotally mounted on a mounting frame 2, and further a rotation supporter 63 having a shaft part 32 at the tip end, which is supported with a shaft at the frame 2, is hanged down from the one side in the direction of the width of the operating handle 3. Also, a circular arc receiving part 67 with the part 32 acting as the center of rotation thereof is provided on the other side in the direction of the width of the handle 5. And when a cover 8 is closed on a cover 7, the part 67 is slidably supported with a projection 61 having a circular arc surface 60, and the handle 3 can be smoothly rotated around a handle shaft 33 which acts as the center of rotation. Furthermore, since the handle 3 is provided with the part 63 only on the one side in the direction of the width thereof, a cradle, a reversing spring 6 and the like may be simply incorporated from the other side in which the part 63 is not present and at the same time the opening and closing operation may be smoothed.

摘要： PURPOSE:To provide an integrator in which the excess current carried in a cable run and the excessive use of power are detected to improve power managing property. CONSTITUTION:An integrated pulse 5c outputted from an integrated pulse generating part 100a formed of a current-voltage converter 2; an effective value arithmetic circuit 3; a V/F converter 4; a frequency demultiplier 5; a display counter 6; and an external pulse output circuit 7 is inputted to a WDT 10 to generate a voltage corresponding to an increase in integrated value of the current supplied to a load 33. This output voltage 10a is compared with the standard voltage 11a of a comparator 11, and when the output voltage 10a exceeds the standard voltage 11a, an alarm signal 11b is outputted, whereby the excess current carried to a cable run 32 and the excessive use of power are detected.

摘要： PURPOSE:To attain wire saving in the case where plural number of data possessed by a circuit breaker for wiring are transmitted to a controller as well as to increase withstanding property of data to noise, an induced voltage and current generated at a breaking time and so on. CONSTITUTION:A sensor circuit section 8 to monitor a cable run condition and a transmission unit 15 which carries out data exchange between it and the sensor circuit section 8 and also carries out data exchange between it and a controller in a multiplex transmission system, are housed in a wiring use circuit breaked body 1. The sensor circuit section 8 has a sensor 3 and a sensor microcomputer 7 to carry out operation processing on the output signal. The transmission unit 15 has a transmitting microcomputer 10 which carries out data exchange between it and the sensor microcomputer 7 and also carries out data exchange between it and the controller. An insulating circuit 14 is interposed between the transmitting microcomputer 10 and the sensor microcomputer 7.

摘要： PURPOSE:To stabilize a power source at the time of short circuit, precisely detect cable information, and improve assembly property by using a current detecting device having two current devices for detecting a current having smaller than a determined standard value and a current larger than the determined standard value, respectively. CONSTITUTION:When the current of a cable is smaller than a standard value, the output signal of a current detecting circuit 1 having a first current transformer 8 is processed in a control circuit 3 to output cable information such as current value and power. When the current is larger than the standard value, the output signal of a current detecting circuit 2 having a second current transformer 9 is compared with a set level, and when it exceeds this level, the detection signal of overcurrent is tripped, and inputted to a circuit 5 to start tripping a device. At the time of short circuit, the output signal of the circuit 2 is directly inputted to the circuit 5. Although the voltage between phases is lowered, the output of the circuit 4 can be stabilized since the output of the current transformer 9 is inputted to the power source circuit 4.
