Surge Protective Devices (SPDs) provide the best protection from both externally and internally generated surges when located as close to the building distribution system aspossible. For cost and space reasons many buildings only include one SPD located at the main incoming load center and do not cascade SPDs throughout the building as recommended by IEEE. The new Siemens QSPD Series of SPDs are economical and easy to install in most panels throughout a building so that whole facility protection can be obtained. The QSPD Base model is an additional option for applications that require minimal features, while offering quality surge protection. See the Siemens Boltshield web page and brochures for more information.
