Abstract

PURPOSE:To enable monitoring of trouble in a semiconductor switch by detecting that a current flows through semiconductors one conducting in positive half cycle and the other conducting in negative half cycle in the same time zone. CONSTITUTION:When semiconductor switch or semiconductor elements 21, 22 of semiconductor breaker 2 malfunctions, a trouble detector 3 detects that load current flows through the semiconductors 21, 22 in the same period to thereby indicate trouble via a trouble monitor 4 using the output signal of the detector 3.
