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

Would you care to elaborate on the difference between a protector used in homes versus the PI?
A PI will disconnect (or not connect) to the pole if voltage is too high (ie 140 volts) or too low (ie 80 volts).
A house protector has a let-through voltage of 330 volts. That means that 120 volt protector does nothing until voltage well exceeds 330 volts. It does no disconnecting.
A PI maintains a disconnection for as long as necessary (ie seconds or days).
A house protector is only designed for transients that a microseconds. Datasheets for those protector parts rate the device using a classic 8/20 microsecond transient.
A PI disconnects power if polarity is reversed. A house protector ignores polarity.
Above anomalies are examples of what is subjectively called a surge. Some may argue that many above examples are not surges. They would be correct - technically. But a technical definition is completely irrelevant to marketing's interpretation.
A PI is designed for common anomalies found in campgrounds. A house protector is designed for other anomalies typically problematic for homes.
