Eaton Magnum DS (MDS) / SBS — common questions
What is the difference between Magnum DS and SBS?
They share a catalog-number grammar, which is why one decoder reads both. The decoder reports which family the number belongs to along with the frame, rating, interrupting capacity, trip unit and mounting.
My Magnum breaker number is longer than the example — will it still decode?
Yes. The decoder accepts both the short frame designation and the full 25-character catalog number, and reports every field it can resolve from what you enter.
