What are some types of surge protectors that are mounted in panels?

Most every panel manufacturer makes their own that can be plugged onto the bus bars of their panel.

For the money, I usually use Delta brand. Their arrestor uses silicon oxide instead of the metal oxide varistors.

There are other technologies available, some of which are sophisticated and expensive. Visit
check out the back issues for more on this topic.

Don't forget that the arrestor at the service is only part of the solution, point of us supressors are also needed for complete protection.

Few things are harder to put up with than the annoyance of a good example.

What is the best location for a surge arrestor? ie. Service head, meter enclosure, service disconnecting means (line side)?

I usually use the Siemens kind I think they are Ukranium Oxide varistors, but they mount right inside the service panel.
Has anyone ever seen these units last more than one hit ?
They are used in DC drives and everytime they get a hit they go up like a roman-cnadle and also wipe out the SCRs. Went through a bunch of them one year.

Schotkey diodes (not sure if I'm spelling schotkey correctly)in a lattice array are the best. They dissipate the electrons throug many diodes in the array.
Nice and efficient

It's spelt Schottky, at least it was when I was at school,they may have changed it since then.
