Electrical naming standards in IEC

Electrical naming standards in IEC

Electrical naming standards in IEC

(OP)
Hi

Does anyone know if there are any specific IEC standards which has guidelines for assigning tags/names to electrical symbols?
For example, CB for circuit breaker, CR for relay contact, XF for transformer etc.?

I referred IEC 61082 & IEC 60617 and couldn't find any specific information although IEC 60617 has a letter assigned to each function class.

Thanks

IEC 81346, which supercedes IEC 61346, is the official reference. Unfortunately it isn't a very definitive standard and leaves plenty room for interpretation, or just plain making-it-up-as-you-go-along.

Moeller have made some effort to define the letter designators for electrical components on pages 10-3 and 10-4 of this link. Their list seems to be fairly close to what I'm familiar with.

Thanks Scotty.

That linked helped.

Star for ScottyUK, I went through the same issue about a year ago, and came to the same conclusion, although I wasn't able to find the Moeller reference at the time, which would have made it much easier.
