Siemens believes today’s residential surge protectors come up short when protecting today’s modern home filled with smart appliances and electronics. This is why we developed our FirstSurge commercial class total home surge protectors. Installed at your load center, FirstSurge will stop surges before they get into your home. FirstSurge is offered in three levels of protection depending upon geographic location and the storm activity where you live. When FirstSurge wears out, its commercial class 3-stage notification diagnostics immediately alerts you that it needs replacing. Knowing you're surge protected with commercial class protection gives you peace of mind that your smart appliances and electronics will always be surge protected. Make Siemens FirstSurge the first surge protector installed into your home.
