Ratings apply to circuits with voltages no greater than those listed.

When protected by any circuit breaker, including thermal-magnetic and magnetic-only, meeting the size limits in Table 35.
3
When protected by any Class J time-delay fuse, meeting the size limits in Table 35.
4
Above 240 V, all lines must be switched.
5
50 A Resistive, maximum 277 V. All others rated 40 A Resistive (above 277 V).
NOTE: This table lists the maximum SCCR of the component when protected by any circuit breaker or fuse. If the
maximum component SCCR is 100 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.
