Re Duplex or Twin Circuit Breakers:
I needed to get a twin 15/15 amp twin breaker for a Murray Panel. Home Depot had two nearly identical ones: Cutler Hammer BD1515 (with the "rejection tab" feature) and the BR1515 without the tab.
I had not noticed if the mating contact in the panel had the notch for the tab to go into, so I bought the BR1515 that did not have the rejection tab.
As it happens, the contact in the panel was notched.
All is well. It works fine.
Questions:
The shelf label at Home Depot said that the BR1515 was "current limiting" (I think) and the item cost $15.
The other one (BD1515) with the tab said "non current-limiting" (I think) and only cost $9 or $10.
Besides the presence or absence of the tab, what other differences are there between these items that explain the price difference?
Should I be replacing the breaker I already installed with the kind with the rejection tab, now that I know it fits? Am not concerned about the price but about any other issue that I don't undertand.
I have been unable to construct a Google search that provides me with an answer.
Thank you.
