Breaking capacity hits 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that cover most industrial service-entrance and feeder applications.
At 415 V the 75.6 kA interrupting rating gives solid headroom for high-fault panels, especially when coordinating downstream with smaller MCCBs or MCBs. The thermal derating curve is published: the breaker holds 16 A up to 50 °C, then steps down to 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C. For panels running above 50 °C ambient, factor the continuous load against these numbers rather than the 16 A nameplate.
