It carries an interrupting capacity of 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V — covering high-fault industrial feeds and transformer secondaries.
The 400 A rating holds up to 50 °C ambient. Above that, it derates: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Size the load accordingly; a 400 A feeder in a 60 °C panel is effectively a 350 A breaker.
The evidence provides interrupting ratings at 240 V (242 kA), 415 V (187 kA), 440 V (187 kA), 500 V (121 kA), and 690 V (7.5 kA). A 480 V value is not listed; the 440 V rating (187 kA) is the nearest available figure.
