Its continuous ampacity is 50 A at 40 °C, and it holds that full rating up through 50 °C; above that it derates smoothly to 45 A at 70 °C. The interrupting capacity is what decides whether this breaker clears a fault without blowing up: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
The breaker measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint that drops into most existing panel cutouts without modification.
