CT physical size

[PeterS84]

Hi All,

Is there any 'magic equation' that allows to estimate the physical size of CT (i.e. length, width, height) based on the turns ratio, VA rating and type of core? How can I actually make sure that the CT will fit where I want to put it (in a cubical for example).
I mean protection CTs here.

Thanks in advance

It's called a catalog.

Peter - Welcome to the forum. Take a look at GE Industrial's website. Specify the CT characterisitics and get drawings.

Other suppiers may have similar websites, but I haven't found them.
