What is an EMP Shield?

The EMP Shield is electromagnetic pulse, Solar Flare, and lightning protection system designed to exceed the requirements of MIL-STD-188-125-1 for shunting over-voltage spikes.

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

Built to exceed military standards (MIL-STD-188-125-1), EMP Shield begins pulling excess electricity from the electrical system in less than 500 trillionths 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 500 trillionths of a second. EMP Shield also designed to continue protecting through the expected durations of the E2 and E3 spikes produced by a high-altitude electromagnetic pulse. 

EMP Shield has also been tested to all other military EMP Standards. Our devices are also UL 1449 compliant and have been tested at Intertek. See below for all military certified testing.


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. Since the shunting is completed incredibly fast (500 trillionths of a second), the over voltage is pulled away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeed™ and it ensures no heat is generated within the electrical system which protects all electronics connect to the system.

What is an Electromagnetic Pulse (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 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 nation’s 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.

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. We have many solar system models all specific to your systems maximum input voltages. If you have questions about which model you will need for your solar system send us an email or give us a call: or 620-412-9978.

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 and most installations take 15 minutes or less. 

Is the EMP Shield attached to my home's breaker box?

Yes, the home model attaches to your home breaker box. We have 2x models. The SP-120-240-W model mounts on the wall beside your breaker box and the SP-120-240-RL model mounts inside the breaker box with a small LED box just outside the edge of the breaker box

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.

How does my EMP Shield purchase ship?

EMP Shield utilizes FedEx, UPS, and USPS, to give all of our customers the best possible delivery experience. Our standard shipping is free if shipped anywhere within the continental United States.

In order to deter lost and stolen packages, EMP Shield places a signature requirement for delivery on all sales over $1,000, to ensure the collection of the EMP Shields.

If you have any concerns or questions regarding the shipping process, please contact 620-412-9978.

Return Policy

EMP Shield Offers a 14 day no questions asked return policy. After 14 days, there will be a $50 restocking fee. After 30 days there will be a $100 fee for returned items. EMP Shield does not accept returns from orders after 60 days.  

Our Most Popular Models

Our vehicle models are by far the most popular model used around the world. Protecting more than $5 billion in property, EMP Shield is the World’s only EMP defense technology surpassing all military EMP standards. We are also one of the World’s fastest surge protectors. Our technology begins pulling excess electricity in less than 500 trillionths of a second.

Over 40 Models to Choose From

From large scale power plants to campers and generators, EMP Shield has a model to help protect your property. Defending not only against EMP’s, our Shield protects against lightning, power surges and coronal mass ejection. No other device in the world is capable of doing this. We invented this state-of-the-art technology.
