Time Current Curve Basics: Determining Circuit Breaker Trip Times
WebIt tells us that at 1.5X the rated current the quickest the circuit breaker will trip is forty seconds (1). Forty seconds at 2X the rated current is the slowest the circuit breaker will trip (2). The bottom of the chart is for the magnetic trip of the coil/solenoid; 0.02 to 2.5 seconds at 3X the rated current is the soonest the circuit breaker ...

This is an important and valuable tool in designing a selectively coordinated system. WebNov 15, 2003 · That makes it pretty clear that a QOB breaker would have to be sized per the Inverse Time Breaker column (even if the breaker has an instantaneous trip). It is clear because a QOB breaker would not have an adjustable setting, and it would not be part of a listed combination motor controller.
