2 TRV values are in accordance with ANSI/IEEE C37.06-2009 TRV peak value uc is roughly equal to historic E2 value in ANSI/IEEE C37.06-2000. Value t3, time to voltage uc is approximately 1/1.138 times the T2 value in ANSI/IEEE C37.06-2000.
3 First value is full-wave impulse impulse withstand circuit breaker open or closed. Second value is chopped-wave impulse withstand, applicable only with circuit breaker closed.
