Description
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 load center and do not cascade SPDs throughout the building as recommended by IEEE. 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.
- Fits into existing Siemens load centers
- 35kA surge current protection per phase
- Green/red mechanical visual indicators (not LED) notify homeowners of protection status
- Plugs directly into load center bus for quick installation
