<P>PROBLEM TO BE SOLVED: To provide an overcurrent detection device that has high convenience and can externally transmit electrical information in individual control of a plurality of load apparatuses. <P>SOLUTION: The overcurrent detection device for installation in a distribution board comprises: a current sensor connection section connected with a current sensor for detecting a current flowing through an electrical path; a determination section for determining whether or not a predetermined level of current flows through the electrical path on the basis of a signal from the current sensor; a control section for operationally controlling a load apparatus by an HA control signal in response to a determination result from the determination section; a data output section for transmitting the magnitude of the current flowing through the electrical path and an operation/stop control state of the load apparatus to be controlled, from the overcurrent detection device to outward; an HA terminal section for outputting the HA control signal from the control section; and an indication/alarm section connection section connected to an indication/alarm section for stepwise indicating and voice-reporting the determination result of the determination means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
