Building Protection

PD Devices Surge Protection Devices (SPDs) are 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, electric switchgear and controlgear.

We offer many different Surge Protection Devices for the building industry;

Type 1, Type 2, Type 3, All Mode Protection, Surge Filters and Equipotential Bonding SPDs

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 mode.
