Switch/Relay Contact Naming Convention
Switch/Relay Contact Naming Convention
(OP)
I recently was told by someone from Schneider Electric that there was an IEC standard that covered the standard names given to contacts for relays, switches, etc. Unfortunately, he did not remember the IEC document number. I am speaking of the names like A1, A2 for the contact terminals.
Does anyone happen to either know the number/title for an IEC docuemnt that covers this, or any other resource.
Thanks

It mentions the numbering system only briefly, but it might provide something useful.

It may be like this in theory and practice, but in real life it is completely different.

So is there a guide on converting standards from IEEE to IEC?
RE: Switch/Relay Contact Naming Convention
This gives a code letter for each type of electrical equipment, e.g. K = relay/contactor, R = Resistor, S = switching devices for control circuits etc.)
I don't think it covers terminal referencing numbers though.
