what are these components?
Hi This is a picture of the progressive industries surge suppressor. Does anyone know what these items are?

Progressive, MOV manufacturers and I are in total agreement. Sacrificial MOVs are an urban myth that even identifies one who is educated by hearsay. Who cannot and did not read MOV datasheets.
Progressive effectively identified which types of surges are relevant in the campground. Their protector is designed for such anomalies. Progressive protectors would be ineffective for surge protection of a home. Completely different anomalies require completely different solutions.
Sacrificial (catastrophic) failure is a fire threat. Some 15 million APC protectors must be removed immediately due to sacrificial failure and resulting fires. Many cruise ships now confiscate that protector from luggage. Cruise ships especially cannot risk fire created by sacrificial protector parts.
Effective protection is never from a sacrificial protector part. But many believe otherwise after spending massively on a grossly undersized protector - that suffered catastrophic failure.
Progressive successfully addresses other problematic surges in campgrounds. Please post using technical facts; not empty denials. Explain that box entitled "Absolute Maximum Parameters" that defines unacceptable (catastrophic) failure. Basic electrical knowledge is required.
