Surge protection - Multi-family dwelling with external lightning protection

Surge protective devices protect electric / electronic systems and devices from damage caused by excessively high voltages. This dangerous interference energy is gradually broken down to a level corresponding to the rated impulse voltage.

Please note that the relevant arresters have to be energy-coordinated to ensure interaction of the individual protection stages.
