Original on the left, purchased replacement on the right.
Questioning whether these are equivalent for an old General Electric motor starter overload (CR106).
Seems like slightly different approaches to get a bimetalic bend effect when a specified current flows through each of these. One requires a resistance wire to heat the metal, whereas the newer one incorporates the resistance in the metal? Is that what?s happening?
Does the element do the physical ?tripping? of the OL, or do these do nothing more than generate heat which heats up the separate mechanism that opens N.C. contacts?
Thanks.
