 		 #90706 - That's strange, Erik!

Here in the US the certification of electrical equipment is done by UL, I do not know what the match is in the EU. UL would never certify the MID400 as a mains switch, only as a "subswitch"

Erik,

Look what's further mentioned:

{}

FEATURES
• Direct operation from any line voltage with the use of an external resistor.
• Externally adjustable time delay
• Externally adjustable AC voltage sensing level
• High voltage isolation between input and output
• Compact plastic DIP package
• Logic level compatibility
• UL recognized (File #E90700)
• VDE recognized (file #102915),
– add option V (e.g., MID400V)

{}

What does 'recognized' mean in the context given above? Same as 'certified'?

Best rgds,

--Geert
