Ron, Hasco recently got their HS series relays re-evaluated by UL to the higher dielectric strength---2250VAC between coil and contacts and 2000VAC between contacts. The only problem, as Joe pointed out, the creepage and clearance requirements weren't met for my application so I couldn't use it for Europe.
If you can use it, however, I can fax you a copy of the UL memo stating the new ratings or you can get it from Hasco. Regards, Debbie Olson Boca Research
