Abstract
An electronic overcurrent release for circuit breakers includes a first setting device connected to at least one control input of a microcontroller and configured to set a selected suitable nominal current value in a range between a minimum nominal current value and a maximum nominal current value. A second setting device is connected to at least one control input of the microcontroller and configured to set a selected suitable lag level, the second setting device having a test position. In the test position, the microcontroller has a set fixed test current value, which is less than the minimum nominal current value, and a set fixed test delay time, the microcontroller providing a release signal at a release signal output upon at least one of the phase currents exceeding a value of the set fixed test current value and a time of the set fixed test delay time.
