3 First value is full-wave impulse withstand circuit breaker open or closed. Second value is chopped-wave impulse withstand, applicable only
with circuit breaker closed.
First value is for standard 50 ms/3-cycle interrupting time. Second value is for optional 83 ms/5-cycle interrupting time (see note 1).
