The invention relates to an electric protective device which includes a current limiter (101). The current limiter is arranged to be activated if a predetermined current level above normal current level is reached. According to the invention, detecting means (102) detect whether the increased current level is a fault current or a load transient, and a circuit breaker (103) is arranged to open if there is a fault current, but remain closed otherwise. The invention also relates to a corresponding method, to a circuit provided with the device and to a use of the device. |
