Does anyone have a link or access to an Allen-Bradley thermal overload (heater) chart? I have a one horse, 3 phase motor on a NEMA size 0 starter that I need to sizes OL heaters for, and don't have a chart handy. I used to have a really cool AB slide chart, but someone snarffed it. Any help would be appreciated.

Yes, I looked there first, and suprisingly they didn't have a chart posted. They do have and old service bulletin with a chart on type N heaters, but I need a W. I have a W-50 in now and it seems to be working (the W-29 dropped out after about a minute) but I'd really like to get the right rating.
