Anyone know of anywhere I might get hold of a DC circuit breaker rated higher than 63A? We are currently using the Teresaki 4500 series C63 but want to go higher.

Yes, I know it's a high current but those of you who know me will know why!!!

It's fairly common to use a 400V 3 phase AC breaker (all 3 wired in series) to break DC up to about 110VDC, AC 3 phase breakers can be obtained in 80A, 100A,120A, 150A.
