IP rating of Proteus 3 phase board.ABX4S1/CD

hertzal123
The product data sheet for the above states"IP Rating IP 3X.Thought horizontal surfaces had to be 4X,

or is does that relate only to the installation work?

    Top horizontal surfaces of enclosures do indeed have to be IP4X to meet BS 7671 requirements.


    Although if you had to state one overall IP rating for an enclosure, and other bits (e.g. the front) had a lower rating, then you could only claim that it met the lower rating overall - which I might guess could be the case here. It wouldn't make sense to claim an overall IP4X if the front was only IP3X. Obviously it would be better to give the IP ratings for the top and other surfaces separately (Top & sides: IP4X, Front: IP3X) - but marketing often isn't that logical.
