The Square D - QO250PSPD QO Whole House Surge Protection Device is a robust and efficient solution for safeguarding your home's electrical system against surge damage. This surge protector integrates seamlessly with the QO line of electrical panels, which makes installation straightforward for those already using QO products. Its compact size belies its effectiveness; it does not consume much space in the electrical panel but offers powerful protection. One of the standout features of this device is its high energy absorption capacity, which ensures that it can handle even severe surges, like those caused by lightning strikes or grid fluctuations, without faltering. The visual indicator is a practical addition, providing immediate feedback on the status of the device – it's a simple yet critical feature that helps homeowners know when the unit is functioning correctly or needs replacement. Although designed primarily for residential use, the durability and performance level of the Square D QO250PSPD make it suitable for light commercial applications as well. This device is a worthwhile investment for anyone looking to enhance their home’s electrical safety. It provides peace of mind with its reliable protection, keeping your electronics and appliances safe from potentially costly and dangerous power surges.

I installed numerous (200A panel) copies of the earlier model of the QO plug-on neutral GFCI/AFCI breaker, and had endless problems with nuisance AFCI trips on various circuits - LED lighting, washing machine, kitchen microwave, etc. Ferrite cores, surge suppressors, etc. shouldn't be required to make a circuit breaker function correctly! Siemens should never have marketed those breakers until they had done more development and testing of the AFCI portion of the breaker to better-characterize load profiles to distinguish "true" arc faults from everyday inductive loads. Good news is - these newer-model breakers eliminated ALL of the nuisance-trip issues in my house. Strongly recommended for use in replacing those pesky 2017-2018 (everything up to when this model was released) breakers that have nuisance-trip issues.

Pretty easy to plug into your squareD or compatible power panel. Don't need an extra double pole breaker so saves some money on the install. Hopefully it works for the next lightning storm.
