SIPROTEC 7SJ85

[Amro Protec]

I have a damaged SIEMENS Siprotec 7SJ85 relay its Product code is: 7SJ85-DAAA-AA0-0AAAA0-AM0111-12111B-BAA000-000AC0-CB1BA1-CB1CG0-CG0CL0
and I have another spare 7SJ85 relay Product code is: 7SJ85-DAAA-AA0-0AAAA0-AA0111-12111B-BAA000-000AC0-CB1BA1-EB0
My question is can i swap the damaged one with the spare and change the product code of the spare one of course i will install all expansion modules that were installed in the damaged and install it in the spare.

You really need to take this up with your local Siemens support office.

Go to the Siemens relay configurator and copy/paste both product codes into the <search> bar.
Step through the configurator and the last page will tell you what the specific sequence means, in (relatively) plain English.
If the two descriptions match, chances are good that the relays can replace each other.

Still, verify through your local Siemens representative just to be POSITIVE that things will work as expected.
