I don't know about the Model 3, but at least in the Model S Performance, the main breakers are some short cables with a pyrotechnic charge. When the maximum current is exceeded, the explosives blow up the cables... After all, they are only triggering in excess of 1500 amps. Seems to be difficult to build traditional breakers good for up to 1500 amps which react fast enough. |
