-Cutaway before use, that is... Nice.
This is another <200 Amps 400 VAC 3-phase circuit breaker (exploded view) after final use:
Attachment 32056 Attachment 32057
Pretty decent exterior, right? Opening up by drilling out the rivets shows the mayhem...
Attachment 32058 Attachment 32059
Note the impressive copper blob on the contact point, the heat witness marks & oxidation of the flash arrestors.
"-Just another day at the office."
