The trip time is typically 3 s in the range between 1.1 and 1.8 x I
Electronic current limitation occurs at typically 1.8 x I
means that under all overload conditions (independent of the
power supply and the resistance of the load circuit) the max.
overload before disconnection will not exceed 1.8 x I
the current rating. Trip time is between 100 ms (short circuit
current I
Without this current limitation a considerably higher overload
current would flow in the event of an overload or short circuit.
