Whole House Electrical Surge Protection

Siemens FirstSurge

Today’s homes filled with smart appliances and electronics require constant surge protection to prevent damage. Selecting a surge protective device that delivers the proper level of protection, and knowing when a surge protector needs to be replaced, are the keys to ensuring your home remains protected. This is why we developed FirstSurge, our commercial class total home surge protector.

Installed at your load center (electrical panel), FirstSurge will stop surges before they get into your home. FirstSurge offers three robustness grades to compensate for the storm activity where you live. All surge protective devices are sacrificial and will eventually wear out. When FirstSurge wears out, its commercial class three stage notification diagnostic immediately alerts you that the unit needs replacing. FirstSurge is first in class compared to devices on the market that have only LED notification, or provide no notification at all.

With FirstSurge commercial class protection, you will have peace of mind that your home will always be surge protected. Make Siemens FirstSurge the first surge protector installed into your home.

FirstSurge is Available in 3 Protection Levels

FirstSurge Power (FS060) = 60,000 Amps per phase protection.

FirstSurge Plus (FS100) = 100,000 Amps per phase protection.

FirstSurge Pro (FS140) = 140,000 Amps per phase protection.

Electrical System Protection

A surge, sometimes called a transient or a spike, is a brief burst of energy (voltage and current). The most damaging surges enter through your home’s power, cable and telephone lines. However, the majority of surges originate within the home from the action of motor based appliances like dishwashers, refrigerators, garage door openers, etc.

Siemens FirstSurgeTM stops power surges from entering your electrical system protecting smart appliances, TVs, computers, heating and cooling systems, and more. Every FirstSurgeTM includes commercial class notifiers (LEDs, Audible Alarm, and Red Flashing LED) and supplemental GRM Diagnostics.

Siemens offers three levels of protection for your electrical system:

* FS060 (First Surge Power) = 60,000 Amps

* FS100 (First Surge Plus) = 100,000 Amps

* FS140 (First Surge Pro) = 140,000 Amps

Phone System Protection

There are multiple ways surges can enter the home, including the electrical system, coaxial cable, and also telephone (DSL) lines. Just as with coaxial systems, often surge protection for telephone lines is ignored, exposing modems, computers, and phone systems to dangerous surges. Siemens FSPHONE is a two pair, hardwired surge protector for telephone, DSL or modem connected electronics in residential and light commercial applications. The FSPHONE protects against electrical power surges that can enter through the main telephone connection and is equipped with a failshort device to permanently ground the telephone line in the event of a power cross. The catalog number 'FSPHONE' is designed for indoor applications or can be mounted inside another weatherproof enclosure for outdoor mounting applications. The catalog number 'FSPHONE4X' consists of the FSPHONE plus a weatherproof enclosure to facilitate indoor or outdoor applications. The enclosure is molded of temperature and humidity resistant thermoplastic to resist cracking and discoloration. The cover can be secured with a tie wrap or similar locking device.

Coaxial System Protection

Protecting your electrical service and not your coax cable allows for surges to enter through an unlocked or unprotected back door. To prevent surge damage from Cable TV or Telephone lines, you need to surge protect in the same manner as power by stopping surges at the incoming cable TV utility service.

Whole House Surge Kits

If you have been hit with surges, but unsure if the surge entered from the power, cable, or telephone lines, we offer our combo pack that combines Power, Cable, and Telephone protection within one pack.

Installing all three surge protectors at the same time gives you peace of mind that your home will protected against any surge trying to enter from any of your main utility services.

Siemens FirstSurge Selection

To prevent surge damage, surges need to be stopped at your home’s incoming utility services through the installation of power, cable, and telephone surge protective devices.

Surge exposure map correlating storm frequency and intensity with increasing FirstSurge capacities; Any FirstSurge will protect in all regions, but selecting the recommended surge current capacity increases surge protector robustness to compensate for the surge activity where you live. This practice helps ensure years of operation.

Don't let the next lightning storm or utility company surge damage your home's electronics and appliances, install Siemens FirstSurge today!

    Insurance in the lightning capital of the world
    Living in Florida, the lightning capital of the world I felt my house needed extra protection from lightning and electrical spikes. I could use the device from the electric utility to add whole house protection but I would be paying a monthly subscription on my electric bill. After much research I found that the Siemens FS140 Whole House Surge Protection was the best and simplest device to add to my system. It took my about a 1/2 hour to install. Please keep on mind if you don't know what you are doing hire a professional as high voltages are potentially involved. I'm very satisfied with the install and operation, let's just hope I never needed it. Great peace of mind.

    5.0 out of 5 stars Excellent product but not a DIY project unless you know what you are doing
    Reviewed in the United States on December 26, 2023
    Purchased/Installed the FS140 whole house surge suppressor in July 2021. Been working flawlessly since. Just sits there silently doing its job. Whole house protection at the service entrance is great piece of mind. I do note the price is up substantially since 2021 (thanks covid) but still an outstanding value in my opinion. However, not a DIY project if you are afraid of electricity or uncomfortable with working INSIDE a breaker box. Requires the addition of a dedicated two pole (240v) 20A circuit breaker (not included - purchase separately for your brand of panel) to your existing service panel so (1) make sure you have free space and (2) you will have to access the inside of the panel so BE CAREFUL. The instructions recommend the shortest run possible for the wiring from breaker to the device as well as keeping it close to the neutral and ground bars in the panel. Also, although the instructions did not specify distance from the main breaker, I made sure to put mine first in line (my main comes in the bottom of the panel and the breaker for the surge protector is first on the bottom right as circled in photo) as I figured it could not hurt to do so. This location was also close to ground/neutral in the panel and gave me a knockout close by to mount the FS140 device. Had to move some other breakers to accomplish this so again DO NOT ATTEMPT if you don't know what you are doing. If you are at all unsure of your ability to DIY this I recommend you google and read the installation instructions first to make sure you understand what is expected.

    PROs
    Small footprint
    Easy to Mount
    Clear Instructions
    Impressive protection specs
    Feels substantial/well built
    Visible LEDs report on protection status

    CONs
    May (likely) require additional materials to install
    Not for your average DIYer

    Would I purchase again? YES - even at its current price it is cheap protection and great piece of mind. Far better than relying on surge suppression strips of dubious origin and quality.

    5.0 out of 5 stars very well made
    Reviewed in the United States on May 20, 2023
    I installed this recessed in drywall with the very expensive but very well made mount plate, it looks great this was the only place I could access due to design of my panel - avoid the always live service entrance side for safety!!!! . Anyway this SPD is very highly rated (google it and you get a lot of info), it appears to be very well made the wire is decently long about 3 ft (but make as short as you can per instructions) and heavy 10ga wire much more solid than other items I considered. Yes it is pretty expensive BUT when you think of all the devices in your home the cost is worth it. About a year ago I lost several items in a power outage after a storm and have been considering adding a SPD since.... but after replacing my AC unit (not power related, just worn out), I decided this was something I needed now as we have frequent storms and a few outages every year - think about the hit everything takes as power comes back on all over the area at the same time. Whole home surge protection is standard on new homes so adding it to an older home makes good sense - will it save my stuff???? who knows but much better than nothing. The first one I received was damaged (stuff rattling around inside it) but Amazon replaced it within one day and the installation went very smoothly after that but a quick word of caution: If you dont know how to install this hire someone - it requires some skill and opening then working inside your service panel and cant say this enough: this can be very dangerous IF you touch the wrong thing it can kill you be very careful!!!! great item and Im very happy with my choice

    Reviewed in the United States on November 9, 2023
    The Siemens FS140 Home Surge Protector offers reliable protection against power surges, ensuring your electronic devices stay safe during voltage fluctuations. Its compact design allows for easy installation, and the device provides a sufficient amount of protection from exterior surges. Installation was fairly simple - pop off the circuit breaker cover and install a new 20A circuit and tie the whip into the FS140. I’m not an electrical expert, but it took me about 15 minutes. With Siemens' reputation for quality, the FS140 surge protector is a trustworthy choice for protecting your valuable gadgets and appliances.

    Reviewed in the United States on December 19, 2023
    I haven't had a surge yet, so I can't say if the product works as it is advertised, but I am hoping this whole house surge protector never has to kick in.

    Instead, I will talk about the installation. I did the fancy flush mount installation behind the wall with a face plate. The face plate cost $100, which I thought was a rip off, but it does make the installation clean, it is what it is.

    The installation wasn't complex, but it was laborious because I had to create a wooden frame to house the SPD in between the wall stud and since the stud is so much wider than the SPD if you mount it vertically, you don't have a lot to room to work with given the limited size you have to cut on the dry wall. I needed a 90 degree drill in order to install this SPD.

    If you plan to do an in-wall flush install, I would recommend your install it horizontally.

    After the installation, it looks great, flushed where all the wires are behind the wall.

    Again, I can't tell your how will this thing works with surge protection as I have not had a surge yet, but others who has are saying it works very well. So I guess others' testimony does give me a peace of mind.
