WebOct 20, 2016 · The Time-current curve (TCC) of a thermal-magnetic circuit breaker can sometimes be nested underneath the TCC of an upstream electronic trip circuit breaker. If there is no overlap of the TCCs at any point below the available short circuit current at the downstream panel, the circuit breakers are selectively coordinated.
