Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — meaning it can safely clear faults up to those levels without upstream cascading, which is critical for selectivity coordination in a multi-level distribution system.
Maximum power loss is 4 W.
With a minimum trip setting of 95 A and maximum of 756 A, this breaker provides a wide adjustment band for coordinating with downstream branch circuit breakers. Designed for line protection, it is not a motor-protective device — use it for feeder or main breaker duty in a distribution panel.
