Protecting your home or shop from the threat of EMP is critical. Having the correct components installed to protect your home or shop is just as critical. The best way we know to do that is by taking 3 simple steps highlighted below. The FIRSTSURGE™ PRO 140 KA fulfills one of the most important steps, which is having a quality whole-house surge protection device. In the past we have recommended purchasing one from a selection of online retailers but we kept receiving questions as to which ones to trust, complaints that they were difficult to find and questions as to what was a good price. We have now decided to carry the FIRSTSURGE™ PRO 140 KA so that it is always in stock and at a fair price and can be purchased from a single source along with your Whole-House Ferrites and Broadband Ferrites.


How to Protect your Home from an EMP or Solar CME
Please watch the video below for a more complete understanding of how to protect your home from an EMP or CME.

As you can see from the video, I recommend a three-step approach to home protection.

Step 1: Install custom high-saturation ferrites over your incoming power wires. Normal ferrites will not work well due to current saturation. The ferrites sold here are each individually modified to increase their saturation levels, allowing them to suppress high-frequency energy under higher currents. Note: Most homes require three ferrites (for Line 1, Line 2, and a shared Neutral/Ground). Some homes may have four wires and therefore, would need four ferrites (Line 1, Line 2, Neutral, and Ground). Order now while in stock.

Typical installation shown below. Always consult manufacturer’s instructions, and have a professional electrician do the installation for safety. Please note that ferrites tend to make a humming or buzzing noise when high currents flow through them.

Step 2: Install a quality whole-house surge protection device. Recommended device: Siemens FirstSurge140 (FS140).
We now sell the Siemens FS140, available for order on our website.  Installation should be done by a licensed electrician.

Step 3. Install smaller broadband ferrites around power cords of sensitive electronics. We sell a number of different sizes, as well as some bundles. Please see Individual Ferrites or Bundles.

What makes the High-Saturation EMP Ferrites Special?
The short answer is that normal ferrites will quickly saturate and become ineffective when placed on high-current lines. With my knowledge of electromagnetics, I was able to come up with a unique solution to the problem. See the video below for a detailed explanation.

I believe in this method so much that I put it on my own home. Watch the video below for tips on installation of the ferrites.

These SPDs are used for appliances, electronics, and other residential applications to detect and limit power surges to protect equipment from damage. They mount directly onto the main panel of the service entrance.

Not long ago, we turned knobs and dials to change TV channels or set wash cycles. Now, we’re in the Internet of Things (Iot) era where homeowners are increasingly reliant upon connected devices. To ensure these devices just keep working, today’s home requires constant surge protection. Knowing when a surge protector needs to be replaced is the KEY to remaining protected. This is why Siemens developed FirstSurge, their commercial class total home surge protector. Installed at your load center, FirstSurge will stop surges before they get into your home. FirstSurge offers three grades of robustness to ensure long operational life depending upon the storm activity where you live. The key to remaining surge protected is knowing when a surge protector needs to be replaced. The gap of time between a surge protector wearing out until it is replaced is the time when your home is vulnerable to being hit by surges. When FirstSurge wears out, its commercial class 3-stage notification diagnostics immediately alerts you that it needs replacing. This type of notification results in a far shorter Mean Time Before Surge Protection Restoration (MTBSPR) when compared to standard whole house protectors equipped only with LED diagnostics. 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. When there is a problem, Siemens FirstSurge takes the guesswork out of knowing when it is time to be replaced; an audible alarm beeps, the green LED lights on the device will extinguish and the red service light will flash.
FirstSurge is equipped with ground reference monitoring notifying you a rare safety hazard exists due to a compromised electrical system neutral to ground bond; in this case an audible alarm will beep, the green LED lights on the device will remain lit, and the red service light will flash.

FirstSurge pro provides 140,000 Amp of surge current capacity per phase
NEMA 3R enclosure per Nema/UL requirements.

FirstSurge’s balanced 600-Volt protection ratings means every primary paired conductor (line to neutral, line to ground, and neutral to ground) will knock down surge over voltages to safe levels.

Every FirstSurge electrical AC service protector is equipped with worry free commercial class 3-stage notification; when FirstSurge wears out, its audible alarm will beep, protection status LED/s extinguish, and red service LED flashes.

When 3-stage notification activates, you turn off FirstSurge dedicated breaker, and you contact your electrician to arrange for installation of replacement unit.

-FirstSurge can be used to surge protect any load center brand when connected to a 30A or less 2 pole circuit breaker.
-Every FirstSurge electrical AC service protector is assigned underwriters laboratories highest robustness nominal discharge current of 20kA.
-FirstSurge is designed to surge protect standard residential split phase 120/240, 60 Hz system voltage.
-FirstSurge is constructed using commercial grade NEMA 4X enclosure allowing for indoor or outdoor installations.
-FirstSurge Surge Protective Devices (SPDs) are Type 2 and UL / cUL listed, meeting designated protection requirements.

Installation instructions included to be done by a licensed electrician.
