Abstract
Low voltage, electronic protection device in cases of surges in the specific power supply point.Low voltage, electronic protection device that can be connected to the power supply network by means of a residual current differential switch, of which there is a large quantity in low voltage electrical installations. It includes ways to connect to said power supply network and an earth conductor, characterised in that it also has a control unit that measures supply voltage Us, comparing said Us voltage with a default UUMB threshold voltage, and generating a control signal when said supply voltage Us exceeds said predetermined UUMB threshold voltage for a set time tMAX, and a power unit that, on receiving said control signal from the aforementioned control unit, generates current derivation bursts to the earth that provokes the triggering of the differential, regardless of the circumstance or status of the said power supply network.</IMAGE>
