If you have to ask, you probably don't need it :D
It's a surge protector for shore power. They are expensive.
I imagine the people who have one had a power blast in their coach that fried a bunch of more expensive stuff. I have to admit it hasn't happened to me yet. A pre-emptive strike? You decide.
There are other types of surge protectors that are very affordable.

The cost of repairing the average coach that takes a serious hit is around $3,000.
For around 100 bucks for a surge protector is a small chunk of change for insurance to prevent what can be a real expensive repair.
The $100ish units provide only quite limited protection. They don't protect from miswired outlets or bad neutral connections that put 240V where there should be 120V, nor do they provide any protection against brownouts or similar undervoltage problems. These two are probably the most frequent situations where bad shore power causes damage to RV systems.
Most will give you an indication of an outlet with swapped or open connections, and have some MOVs to provide a degree of protection against high voltage transients, but that's it.
