Above that, derate: at 55 °C it handles 62 A, at 65 °C it drops to 60 A, and at 70 °C it's 58 A. The 75.6 kA interrupting rating at 240 V is the maximum fault current it can safely clear at that voltage; at 415 V that drops to 52.5 kA, at 440 V to 32 kA, and at 500 V or 690 V to 7.5 kA.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard MCCB footprint for a 3-pole 63 A frame.
At 240 V it is 75.6 kA, at 415 V it is 52.5 kA, at 440 V it is 32 kA, and at 500 V or 690 V it is 7.5 kA.
