The TW takes a 428 rather than a 520 chain. Otherwise the O-ring style and brand listed are good choices.
Chain breakage is unusual and may be indicative of inadequate adjustment , extreme usage or result of debris entrapment. As such sprocket integrity comes into question too despite a non-worn appearance. I follow industry guidelines of replacing sprockets with chain as they are an integrated system.
Actually a stock chain and sprockets that has 3,000 miles on them has reached a reasonable life expectancy for a bike that makes occasional forays into the dirt. I would replace all three if I could afford it to avoid premature re-replacement in the future as old sprockets will immediately start shortening life expectancy of the new chain.
