As a device that opens and closes different circuits based on the presence or direction of the control current with an electrical/electronic detection information, when a short circuit or grounding fault in the power system occurs, or when an abnormal condition that causes insulation breakdown or adversely affects the rest of the system occurs, it is used to relay the change in the current that sends the command to detect this and operate the circuit breaker to promptly disconnect the faulty part from the system.
