What's good
- Best published VPR of the whole-house group — 600 V let-through L-N
- Lifetime device warranty, unusual in this category
- Fits beside any manufacturer's load center via a 2-pole 50 A breaker
What's not
- No audible alarm — you have to look at the LED to know it's still protecting
- Eaton's own page is inconsistent on SCCR (22 kA vs 200 kAIC) — ask your electrician to verify against the label
Our verdict
Functionally the Siemens' equal, and its 600-volt let-through is the best number on this page. Choose between the two on warranty style — Eaton's lifetime-device promise versus Siemens' bigger connected-equipment pool and audible alarm.

- Leviton P2120-B — service-entrance installs and meter-adjacent mounting
- Intermatic AG3000 — adding a protection layer at the ac condenser or heat pump
