1
Ratings apply to circuits with voltages no greater than those listed.
2
When protected by any circuit breaker, including thermal-magnetic and magnetic-only.
3
When protected by any Class J or CC time-delay fuse.
NOTE: This table lists the maximum SCCR of the component when protected by any circuit breaker or fuse. If the
maximum component SCCR is 65 kA and a 25 kA rated circuit breaker is used, then the system will be 25 kA as the
circuit breaker becomes the weakest link.
