Main applications
Low Voltage SPD
Very different devices, from both a technological and usage viewpoint, are designated by this term. Low voltage SPDs are modular to be easily installed inside LV switchboards.There are also SPDs adaptable to power sockets, but these devices have a low discharge capacity.
Principle
SPD is designed to limit transient overvoltages of atmospheric origin and divert current waves to earth, so as to limit the amplitude of this overvoltage to a value that is not hazardous for the electrical installation and electric switchgear and controlgear.
SPD Eliminates Overvoltages
in common mode, between phase and neutral or earth;
in differential mode, between phase and neutral.
In the event of an overvoltage exceeding the operating threshold, the SPD
conducts the energy to earth, in common mode;
distributes the energy to the other live conductors, in differential mod
