Claims

[Scope of utility model registration request]

An input/output terminal, an electric line connecting this input/output terminal, an electric line contact provided on this electric line, a zero-phase current transformer installed on the electric line to detect unbalanced current in this electric line, and a zero-phase current transformer of this zero-phase current transformer. a switching element that sensitizes switching in response to the output;
In an earth leakage breaker in which a trip coil that is controlled by the switching element and trips the electrical circuit contact is housed in the container body, an alarm device that is switched to the trip coil and controlled by the switching element is housed in the container body. An earth leakage breaker characterized by housing a trip coil that can be operated from outside the device and a switch that switches between an alarm and an alarm.
