Features
• 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 short-
circuit conditions
• 200 kA interrupting rating provides protection for virtually all circuit
locations
• Small footprint allows more efficient use of panel space
