Abstract
A low-voltage protective device, comprising a first semiconductor circuit arrangement with a power semiconductor, a control and driver unit to drive the first semiconductor circuit arrangement with a control voltage, the control and driver unit configure the first semiconductor circuit arrangement: —in a switching-on process for a switching-on time with a first voltage value, which is a threshold control voltage, of the control voltage, and —increase the control voltage from the first voltage value to a second voltage value, which is a peak control voltage, after the switching-on time, and —increase the control voltage to a third voltage value, which is greater than the peak control voltage, upon detection of a short-circuit current or an overcurrent in a first shut-down step, and to de-energize the first semiconductor circuit arrangement in a second shut-down step.
