It carries 160 A continuously at 40 °C ambient — that's the current it passes without tripping under normal load — and the rating holds flat to 50 °C before it starts to derate: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. At 240 V it interrupts 187 kA; at 415 V it's 121 kA; at 440 V it drops to 75.6 kA; at 500 V and 690 V it holds at 17 kA. If your utility transformer can deliver more than 75 kA at 480 V, you need to verify the actual 480 V rating from the manufacturer, but for the vast majority of installations this breaker has headroom.
