I have a old service panel Crouse-Hinds MP that uses Bryant BR breakers and wondering if Eaton BR is the new equivalent.
Are you sure its listed for original bryant breakers?
Yes, They even call for Westinhouse hqp breaker, I just found this at HD web sight.
"The UL-listed breaker is compatible with Westinghouse, Challenger and Bryant load centers and has a maximum load of 240-Volt."
"Type BR breakers are UL approved genuine replacement breakers for load centers made by Westinghouse, Challenger and Bryant"
Crouse Hinds wasn't proud. They used to list Bryant, Westinghouse/GE, as well as ITE in addition to their own. I always like seeing the circle-W in the fine print on the label.
Have seen a number of Crouse-Hinds panels that said that ITE, Westinghouse were OK for their panels, BR is nothing more then a reincarnation of Zinsco. Murray is easy to find at Home Depot, IMHO always better to use a OEM replacement.
why do you say that?
Are the internals the same?
Are they poorly constructed?

They are not at all the same. BR Bryant and BR Eaton/Cutler hammer are the same. Zinsco is a completely different breaker that are not remotely close.
Regarding the Murray panel it's already been mentioned, but the Murray MP are likely the correct replacement, if the panel schedule is intact it should tell you what replacements are appropriate. MP is likely, BR is possible.

I'm not sure when panel schedules became standard.
People didn't nitpick over such things back in the day.
