StrikeShield™ SPDs (Surge protection Devices) are protective devices for limiting transient voltages and surges by quickly and safely diverting surge current. Their advanced design not only provides all-mode system protection, but is robust enough to provide a long life of protection over repeated transient events.
StrikeShield™ SPDs install in parallel with the service entry. When the incoming voltage exceeds the safe limit, the StrikeShield™ unit reacts in less than a billionth of a second to divert the potentially damaging currents. Depending on the model, the unit’s surge capacity can be as high as 200,000 Amps.
StrikeShield™ SPDs use high-performance protection technology to ensure both safety and long life, including:
- Minimizing component stress using advanced linear sharing design
- Maximizing the repetitive surge capacity using thermally protected MOVs
- Built-in noise attenuation capacitors to help reduce EMI and RFI noise interference
Together, these technical features deliver top-drawer protection even when hit with repeated surge events over the units life. |
