I was looking at the hours it's rated at and how that compares to most relays:

It's a typical automotive-grade relay. Very low contact voltage rating (14v), and only DC resistive current ratings. That's how they get such a high current rating out of such a small relay.

Note that automotive relays should not be used where you have a high voltage difference between the coil and contacts.
