It carries a continuous current rating of 63 A at 40 °C, with minimal thermal derating up to 70 °C (58 A at 70 °C), so the 63 A frame holds its rating across the typical panel ambient range without upsizing. This 3-pole breaker delivers interrupting ratings of 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that cover most industrial LV fault levels. At 500 V and 690 V the interrupting capacity drops to 7.5 kA, which still handles downstream fault contributions on 480 V or 600 V class systems when the available fault current is known to be below that threshold.
