What is an EMP Shield?

EMP Shield™ is the worlds only tested and approved EMP protection technology for an entire electrical system.

The EMP Shield is a very robust electrical surge arrestor, designed to exceed the requirements of MIL-STD-188-125-1 for shunting over-voltage spikes to ground and neutral very quickly.

Built to exceed military standards (MIL-STD-188-125-1), EMP Shield is also one of the worlds fastest whole home surge protectors operating in less than 1 billionth of a second.

EMP Shield is designed to protect an entire home from Lightning, CME (coronal mass ejection, power surges, and an EMP (electromagnetic pulse). Proven and tested at Keystone Compliance, a Federally approved Department of Defense (DOD) testing facility, Our EMP Shield was struck with over 40x EMP strikes with no impact to the device.

MIL-STD-188-125-1 requires that the over-voltage spike from the E1 spike begin shunting 5,000 Amps within 20 nanoseconds. All EMP Shield models start shunting over voltage in less than 10 nanoseconds, while some models are able to begin shunting over voltage in less than 1 nanosecond. The EMP Shields are also designed to continue protecting through the expected durations of the E2 and E3 spikes produced in a HEMP strike.

What is an EMP?

A nuclear EMP is defined as having 3 distinct pulses of voltage/current. The E1 pulse is caused by the gamma rays released during the nuclear reaction. The Gamma rays interact with the electrons and the nucleus of the atoms that make up the atmosphere, and this interaction results in freeing electrons from their atoms. The free electrons ionize the atmosphere (ionization results in electron flow), which can be seen as the flow of electricity through anything that acts as an antenna. All of the wires that make up our nations’ electrical grid make an excellent antenna, which will produce an over-voltage condition throughout the affected area. For an optimally positioned detonation (approximately 300 miles high and over the center of the US), the entire nation will be affected by the E1 pulse. The E1 pulse starts at the time of the detonation of the weapon and continues until 1 microsecond after the detonation.

The E-2 pulse starts at 1 microsecond and continues until approximately 1 second after the detonation. The E-2 pulse is caused by the inelastic scattering (matter bouncing off of other matter) of the matter from the nuclear weapon interacting with the matter that makes up the atmosphere continuing to ionize the atmosphere.

The E-3 pulse starts at approximately 1 second after the detonation and can continue for several minutes. The E-3 pulse is caused by the nuclear detonation distorting the earth’s geomagnetic structure, and then its reconfiguration. As the magnetic lines are pushed out of configuration and then come back into normal configuration, electricity is generated, and flows through the atmosphere until it contacts an antenna (wires).

The antenna that is most affected will be the nations power grid, but all arrays of wiring (even in your house) will act as large or small antennas, and will produce the flow of electricity and over-voltage conditions.

How Does EMP Shield Work?

The EMP Shield can see and protect all the electronics and equipment connected to your electrical system.

This is accomplished by shunting (shorting) the over voltage coming in from the Grid and the voltage surges that are collected within your home.

Whether the electrons are collected within your home or are attempting to come into your electrical system from outside the home (the grid), the EMP Shield will see the surge and protect your electrical system.  The EMP Shield reacts in less than 1 billionth of a second. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeed™

Does this EMP Shield device work in every country?

Yes, it does – but for people ordering outside the USA they need to email us or put a comment in their order as in what country they are planning to use the device. If the unit for their voltages is not in stock we can have one ready to ship in 48-72 hours

Will the EMP Shield work on solar power systems?

Yes, however, we will need the operating voltage of your system (like 12v, 24v or 48v). Send us an email or put a comment in your order as to what voltage your system uses for the panels. If the unit for your voltage is not in stock we can have one ready to ship in 48-72 hours.

Is the EMP Shield hard to install?

No – We recommend you have it installed by a licensed electrician and/or used in accordance with electrical codes and regulations. However, it is very simple to install.

Is the EMP Shield Home Model attached to my homes breaker box?

We have ways for you to mount the EMP Shield box (6″ wide x 2.5″ tall x 3.0″ deep) on the wall beside your breaker box, inside the breaker box and inside the breaker box with a small LED box just outside the edge of the breaker box so you can see the status of all the lines.

Can we use the EMP Shield on our boats, vehicles, or aircraft?

Yes you can. You need to email us or put a comment in your order telling what brand, model and operating voltage your boat or aircraft uses.

Can you also comment on natural occurring EMP events? Such as Sun Flares?
Thanks, RLT

Just how would your devises protect a car that is not plugged into a power source?

I’ve read about wrapping electronic items that are not plugged in into a foil protected and sealed environment to preserve their electric functionality should a strong EMP occur. Is this still a good idea or should we keep everything plugged in with an EMP house shield. Seems like having a back up solar system with solar generator unplugged but wrapped would allow it to work should the entire power grid system go down for a long period and solar is needed for barely sustainable nrg. Is this a reasonable approach? Just doesn’t seem like plugging everything in just to make… Read more »

Are the units that you sell to the military the same as the ones available commericaly and if they are more robust are the available for purchase?
