Latest Patents

Eun Sik Park holds a patent for an "Earth leakage breaker having built-in trip module type circuit breaker." This invention is designed to be installed between a power supply and a load. It features a trip module that can cut off the line in case of an overload. The earth leakage breaker includes a current transformer (CT) that monitors instantaneous current and a control circuit unit that processes this information. The control unit measures the instantaneous current value over time and calculates the slope of the current. If the slope exceeds a predetermined overcurrent value, the system determines an overload state and outputs a signal to actuate the trip module, effectively cutting off the line to prevent damage.
