CT36 - does it have an internal breaker?

[Cableaddict]

I wasn't thinking today, and used a concrete grinder plugged into my CT36.  After a few minutes, the CT36 shut down.  It's been over ten minutes now, and it still won't start.

I can't find ANYThNG online about internal protection, though i assume it must have some.

Tell me I didn't jus burn it up!  (Even if I did, tell me I didn't.  [big grin] )

What's my next move?

thx.
