confused about what replacement heating element to get for water heater

Hello.
I have a 6 year old AO Smith EC2 52 210 electric hot water heater (50 gallon) with an upper and lower heating element. I am looking to replace the heating elements in the hot water heater but am confused about the which ones to use. The rating on the hotwater heater rates the elements as 4500w/240v but has an alternate rating of 3500w/208v a-6. I can see stamped on the base of the element on one side it says '4500w 240v' and on the other side is says 'alt 3500w 208v'. I looked at home depot and they do not have any 208v elements. I ended up buying 2 4500w 240v elements but i'm not sure if I should install them or not. In case this is helpful the water heater is connected to a 30amp breaker.

All of this seemed so straight forward and now i'm confused and worried about starting a fire or something.
Any ideas?

Those elements can be used on either 240 or 208 volts. The wattage the element consumes is different for each voltage. If your house is wired with the US standard of 120/240 volts then that element will work.
