Breaking capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V, so it handles high-fault utility feeds without cascading upstream. The 125 A rating holds flat from 40 °C to 50 °C; above that it derates gradually to 114 A at 70 °C. The 70 mm depth and 101.6 mm width fit standard MCCB panel cutouts.
