Claims

[Scope of utility model registration request]

A main circuit conductor that has a main circuit contact, connects a power supply to one end and a load to the other end, a zero-phase current transformer that passes through this main circuit conductor as a primary side, and a leakage current to the load side. a control circuit consisting of an earth leakage detection circuit section and a capacitor that opens the main circuit contacts when an earth leakage detection current flowing to the secondary side of the zero-phase current transformer exceeds a rated sensitivity current when an accident occurs;
passing through one end of a series circuit of a push button switch and a capacitor of the control circuit as a primary side of the zero-phase current transformer;
An earth leakage breaker comprising a tripping operation test circuit connected to one of the main circuit conductors and having the other end of the series circuit connected to the other of the main circuit conductors.
