My assumption was that a device rated at 380VAC was rated to 380V RMS. Are you suggesting that this is a DC rating? Even the phony SSRs in the link I posted earlier seemed to have a 600V device in them: http://docs-europe.electrocomponents.com/webdocs/133a/0900766b8133a375.pdf So I think that the SSRs are actually intended for the supply voltage on the label. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
