1 Optional 50 ms (3 cycles) with 125 Vdc or 250 Vdc trip voltage.2 TRV values are in accord with IEEE C37.06-200X, Draft 7.4 (March, 2006). TRV peak

value Uc is roughly equal to historic E2 value in IEEE C37.06-2000. Value t3, time tovoltage Uc, is approximately 1/1.138 times the T2 value in IEEE C37.06-2000.

3 First value is for standard 83ms/5-cycle interrupting time. Second value is foroptional 50ms/3-cycle interrupting time.

4 First value is full-wave impulse withstand circuit breaker open or closed. Secondvalue is chopped-wave impulse withstand, applicable only with circuit breaker closed.
