PURPOSE: An assembled power distributing unit making possible monitoring is provided to minimize time and costs for installing an additional measurement apparatus by connecting them to a circuit breaker through only a screw. CONSTITUTION: In a device, a terminal for a main circuit breaker is installed on the top of the case and it is connected to a main circuit breaker power source and a line. An additional terminal is recessed in the surface of the case and is connected to another terminal outside and is connected through a branch line. In a sensor unit, at least one of a current sensor(20), a voltage sensor(23), a temperature sensor(24), and a current leak sensor(22) is connected to the terminal for the main circuit breaker or the branch blocker. An A/D converter(30) converts analog information measured at the sensor unit into digital. A center operation controller(40) processes the digital sensor information transformed in the A/D converter. |
