These custom ferrites are made of a special high-frequency material and uniquely modified to help prevent high-current saturation. A ferrite is clamped around the insulated incoming power wires in your breaker panel. Most homes require three ferrites, but a few homes may require four ferrites (see video below).

Ferrite dimensions: Inner Diameter 0.72″, Outer Diameter 1.5″, Length 1.9″.

What are high-saturation ferrites?
Ferrites are devices that clamp around power wires to reduce high-frequency current transients. Most ferrites will saturate and stop providing protection when more than a couple of amps flow through the wires. The custom-made, high-saturation, auto ferrites sold here are modified to allow significantly more current through the part before saturating.

Ferrites can withstand any normal vehicle transient as well as a nuclear-generated EMP without damage.

When to use high-saturation ferrites?
Clip-on high-saturation ferrites are used in four scenarios:

1. High current is flowing through the wires, and you can’t easily get to the ends of the wires to feed them through a toroid.
2. High current is flowing through the wires, and a clip-on broadband ferrite is not large enough to go around the wire bundle.
3. There is not enough space to fit a large toroid.
4. The application is such that a solid, non-hinging ferrite is preferred.

High-saturation ferrites are available for the whole-house and automobiles.

When to use broadband ferrites?
Clip-on broadband ferrites are often used to protect small appliances and electronics (e.g., computers, TVs, etc.). They simply clip around the power cord. They can also be used on solar power generation wires and other applications where ease of application is desired.

When to use toroid ferrites?
Toroid ferrites are great to use when you can feed the wire bundle through the ferrite. A good example is when trying to protect solar power generation system batteries. Simply disconnect the leads from the battery, feed through the toroid and reattach the leads to the battery.

How to install ferrites?
Broadband ferrites clip around wire bundles.
High-saturation ferrites clip around individual high-current wires.
Toroid ferrites are placed around wire bundles by feeding the wires through.
