isn't the SSCR of a breaker different then the AIC?
SCCR applies to the panel, AIC applies to the breaker, which are you asking about?
AIC applies to protective interrupting devices such as circuit breakers and fuses. The unit of measure for AIC is Amps RMS Symmetrical. This figure, which is typically in range of 5000 to 200,000 amps,describes the maximum fault current that the protective device can clear safely, without welding closed or causing damage to equipment or personnel.
SCCR applies to complete pieces of equipment or components such as dimmer racks or subassemblies such as dimmer modules. The unit of measure is also Amps RMS Symmetrical, and describes the maximum fault current that the equipment can withstand safely—or the maximum available fault current of
the feeder to which the equipment can be safely connected.
