Know before you buy
This device is designed to be installed directly at your home's electrical load center, also known as your breaker panel. Because it is a hardwired unit, professional installation by a licensed electrician is recommended to ensure it is properly integrated into your home's electrical system.
The device features clear LED status indicators that provide a visual check of your protection status. Additionally, it includes an audible alarm that will sound if the unit has been compromised or requires replacement, ensuring you are never left unprotected without knowing.
The FSPD140 is rated for 140,000 amps, providing robust defense against high-energy surges caused by lightning strikes or utility grid fluctuations. However, it does not include EMI/RFI noise filtering, so it is intended for primary surge mitigation rather than cleaning up minor electrical line noise.
This is a single-phase device designed for standard residential electrical systems operating at 50/60 Hz. It is suitable for most modern homes, but you should verify your panel's configuration with an electrician before purchase to ensure compatibility.
The device comes with a 2-year warranty, though its actual lifespan depends on the frequency and intensity of the electrical surges it encounters. The integrated LED and alarm system are designed to alert you the moment the unit's internal components have reached their capacity and need to be replaced.
