Why would a timing chain brake

What causes a timing chain to brake. Too much rpm, too much load, defective manufacturing ? My timing chain had 3-4000miles on it and it came apart and not at the link. Brand new motor done.

You should have just kept the original thread going, since it contained info about what conditions the engine was operating under when the chain broke.
