An electronic circuit breaker (1) is provided with a load current characteristic calculation unit (17) and an output unit (20). A load current characteristic calculation unit (17) calculates a short-time load current characteristic, which is a current characteristic of a load in a short-time region, on the basis of the peak value calculated by the peak value calculation unit (12), and calculates a short-time load current characteristic, which is a current characteristic of the load in the short-time region, on the basis of the effective value calculated by the effective value calculation unit (13). A long-time load current characteristic, which is a current characteristic of a load in a long-time region, is calculated. The output unit (20) outputs load current characteristic information including the short-time load current characteristic and the long-time load current characteristic calculated by the load current characteristic calculation unit (17). 电子式电路断路器(1)具有负载电流特性计算部(17)和输出部(20)。负载电流特性计算部(17)基于由峰值计算部(1
