Benefits
Series combination ratings with branch circuit breakers allows broad range of coverage; independent of breaker manufacturer
Current limitation for non-inductive circuits provides Class T current-limiting response to maximum ground fault and shortcircuit conditions
200kA interrupting rating provides protection for virtually all circuit locations
Small footprint allows more efficient use of panel space
