I did a quick search around... any manually resettable thermostats; apart from the ones on Amazon. I'm not sure if I'd trust them as they don't come from a reputable manufacturer (and they are a safety device afterall). The closest match I could find would be either Digikey 480-6152-ND or Mouser 682-1NT01L-7949 (Note the Mouser part is only rated at 140C, but should be fine for the brew boiler at least; maybe not the steam boiler). Both have a rating that exceeds 10A, so should be good for 1200W elements and both have a working temp well above 150C. Only issue is they both automatically reset, so if you are having an issue they will cut in and out instead of click out (and then you have more of a permanent; albeit resettable; record of what happened).
If the terminal was loose, there would have been a higher resistance which could have caused localised heating: which in turn leads to the device tripping. Kind of like a redundant self protection of that part. So loose terminal might explain why it tripped out initially (which is much better than the boiler actually heating up that hot; which could cause heating element damage).
