摘要:
An arrangement for protecting an electrical facility from overvoltages having an overcurrent protection facility arranged in a first series circuit and a shunt circuit arranged between the overcurrent protection facility and the electrical facility to be protected, the shunt series resulting in a second series circuit, wherein a diode for discharging transient overvoltages is arranged in the shunt circuit, which is conductive if a voltage threshold is exceeded, as a result of which the current resulting from the overvoltage can be passed through the shunt circuit to the facility to be protected into the second shunt circuit, where a first inductor is arranged in a series connection to the diode, the diode is connected here to a first diode terminal on the first series circuit and is connected to a second diode terminal on the first inductor, and where the overcurrent protection facility is not triggered prematurely by temporary overvoltages.
