DC Circuit Breakers
DC Circuit Breakers
(OP)
Does anyone have any advice on choosing circuit breakers to operate at DC? Looking at a 725 VDC 2 wire, ungrounded system, it seems like I'm going to need to series at least 3 poles and break the return path too (another 3 poles)...
It sure would be nice to be able to do this with only 1 CB per circuit...any ideas?
looking at 100 - 800 amp frame sizes...
Thanks a lot!
