SIEMENS CANADA BSPD2A100 100kA 2-Pole 1PH 3W BoltShield Surge Protective Device

Surge Protective Devices (SPDs) provide the best protection from both externally and internally generated surges when located as close to the building distribution system as possible. For cost and space reasons many buildings only include one SPD located at the main incoming panel and do not cascade SPDs throughout the building as recommended by IEEE. The new Siemens BSPD series of SPDs are economical and easy to install in most panels throughout a building so that whole facility protection can be obtained.
