Abstract
The present disclosure relates to an earth leakage breaker system with a leakage current limiting function, which can enhance leakage current limiting efficiency by additionally expanding areas of an input-side leakage current limiting unit and an output-side leakage current limiting unit that perform the leakage current limiting function and can ensure stable leakage current limiting operation by implementing the input-side leakage current limiting unit and the output-side leakage current limiting unit with enhanced corrosion resistance.
Claims7
An earth leakage breaker system with a leakage current limiting function, comprising:
- an input terminal to which an input-side wire is connected;
- an output terminal to which an output-side wire is connected;
- an earth leakage breaker unit of which both ends are connected to the input terminal and the output terminal and which disconnects an electrical connection between the input terminal and the output terminal when an overcurrent flows;
- an input-side leakage current limiting unit that is disposed between the input terminal and the earth leakage breaker unit to limit an input-side leakage current and includes an input-side conductor area expansion plate which is electrically connected to an input-side ground terminal and expands a conductor area of the input-side ground terminal to limit a leakage current;
- and
- an output-side leakage current limiting unit that is disposed between the earth leakage breaker unit and the output terminal to limit an output-side leakage current and includes an output-side conductor area expansion plate which is electrically connected to an output-side ground terminal and expands a conductor area of the output-side ground terminal to limit a leakage current,
- wherein the input-side conductor area expansion plate includes:
- an input-side first conductor area expansion plate to which the input-side ground terminal is electrically connected and which expands a conductor area at the input-side ground terminal;
- and
- an input-side second conductor area expansion plate, which is stacked on an upper portion or lower portion of the input-side first conductor area expansion plate and further expands the conductor area at the input-side ground terminal.
