Note 3: The Circuit Breaker fault is enabled only when no other fault has occurred prior to exceeding the 52mV threshold. If another
shutdown event occurs first (SOA shutdown, UV shutdown, OV shutdown, Disable shutdown) then circuit breaker fault
sensing is disabled and held disabled until the gate is fully discharged and the trip hold time has passed. See Figure 9 for
details.
