Your Opinion Please
(OP)
Please look at the photographs at this link I just set up.

I am looking for insights, facts, and real knowledge about these products.
To be honest I do not like these devices. Many use them and claim "surge protection"!!!. But I do not see any value in these devices to protect controls. It seems to me that by the time a spark occurs, everything I value is already gone. Not only that, but it seems to me that if lightning has come through miles of air just to get to me, a little more sparking will not help.
But I am not an electrical engineer, so I look forward to your comments. We use many other devices that we know work well. But I would like to have more assurance of what I am saying, or correct me if I am wrong.
Thank you.

Regarding the two lower photos, they may be 600V-class gapped silicon-carbide arresters.

On the down side, these devices can and do fail, generally in the shorted condition. This will not generally cause any consequential damage to your protected equipment, but will shut you down for a while.
These devices are fast enough to limit peak voltages effectively. The specs for the devices will indicate the maximum peak voltage downstream equipment will see.
In the past, there has been a lot of junk sold as surge protection. Stick with reputable manufacturers with UL-listed equipment, and be suspicious of any magical claims.
Don't forge to provide protection for ALL incoming lines, including control circuits, instrumentation circuits, telephone lines, 10Base-T lines, etc. Anything coming in from outside is a risk if you're located in a region with a lot of lightning.

Good Luck!

Here is a link to a competitor of Joslyn's since I can't find theirs anymore (I think they have changed hands recently). If you click on their "learning more" link they offer some decent basic information without a lot of hype.
