Siemens QSA2020SPD Whole House Surge Protection with Two 20-Amp Breakers (Siemens Panels Only)

Siemens QSA2020SPD: Whole House Surge Protection

Safeguard your home’s electrical system with a surge protection device designed to cover the entire panel and every connected circuit. The Siemens QSA2020SPD installs in the space of two standard breakers while still including two single-pole breakers, so you don’t lose any available slots in your Load Center. Once wired into a Siemens panel, this SPD shields not just the two circuits it’s connected to, but the whole panel from voltage spikes and power irregularities that can occur during storms, utility fluctuations, or device faults.

With an initial clamping level of 240 volts, the unit reacts to surges quickly, helping to maintain cleaner power delivery to your home electronics. Built for durability, it relies on robust components designed to handle repeated surge events while you continue daily use of lights, computers, TVs, and smart devices without interruption. LED indicators provide a clear protection status, letting you know at a glance that the protection layer is active.
