What's good
- All-metal build in a category of disposable plastic strips
- Diagnostic LEDs actually tell you protection state and wiring faults
- Isolated filter banks keep noisy loads from polluting quiet ones
What's not
- Point-of-use only — the last layer, not the first
- Bulky right-angle plug and metal chassis won't hide behind furniture
Our verdict
The panel SPD can't see surges generated inside the house, which is most of them — this is the layer that does. One at the desk and one at the media stand completes the layered protection the panel device starts.
Compare with the alternatives
- Siemens BoltShield FSPD140 — the default whole-house pick on any brand of panel
- Eaton CHSPT2ULTRA — a lifetime-warranty alternative at the top of the market
- Square D HEPD80 — the proven value pick, especially on square d panels
- Leviton P2120-B — service-entrance installs and meter-adjacent mounting
- Intermatic AG3000 — adding a protection layer at the ac condenser or heat pump
