I was just wondering, how much mercury is in mercury relays such as 80
amp three pole relays. A website claims that even a 35 amp single pole
relay contains 251 grams of mercury, which is hard to believe.

Just shake it! You can probably feel the mercury sloshing around
in there. Yes, the huge old mercury contactors had an amazing
amount of the stuff in them.
