It carries a continuous 200 A at 40 °C through 50 °C, then derates linearly to 176 A at 70 °C, which is the thermal limit you design your enclosure around.
This breaker delivers 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. Those are the interrupting ratings at each voltage level — not a single number you derate. If your service entrance fault current is 100 kA at 480 V, this breaker covers it with margin.
Factory-fitted with 2 auxiliary switches HQ and an undervoltage release (UVR).
Physical fit and panel layout
Dimensions: 140 mm wide, 158 mm tall, 70 mm deep. At 44.5 W maximum power loss, you need to account for heat dissipation in the enclosure; don't stack it tight against other high-loss devices without a thermal calculation.
