They seem to work well for industrial applications.

Telemecanique's older DC contactor range is excellent, just to prove that I don't have a permanent downer of Telemecanique's products like some people think!
Hubbell also make DC contactors, although I haven't used them on a 'serious' job. They did well on a development rig where we abused them somewhat.
There has been discussion of this on Eng-Tips before. Try the search function. Try Thread237-64659 for starters.

I'm getting a great education!

Sticking in somebody else's contactor can be a pain in a certain body part if there was just enough room for the original part. I have seen instances where it was necessary to rewire a control panel or attach an extra box because of the issue.
