China SPD 40KA lightning arrester surge protection device factory and manufacturers

SPD 40KA lightning arrester surge protection device

Short Description:

Suitable range

TU2 SPD is generally parallel connected onto the front circuit of the required protected circuit equipment, as close as possible the down circuit terminal. The SPDis connected with one end of the circuit conductor(phase line L or neutral line N), and the other end of the connecting line of equipment grounding device, for the lightning equipotential connection.
