Its breaking capacity hits 70 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which means it can safely interrupt fault currents up to that level on a 400 V distribution bus without upstream cascading. The 3D protected poles description confirms all three poles are monitored.
The 105 mm width, 161 mm height, and 86 mm depth take standard panel cutout space for a 160 A frame. IP40 front face keeps tools and fingers out; IK07 impact rating handles incidental panel knocks. Overvoltage category III confirms it's designed for fixed-installation distribution panels.
Breaking capacity across the voltage range: 100 kA at 240 V, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, 10 kA at 690 V — all per IEC 60947-2. Also rated per UL 60947-4-1: 85 kA at 240 V, 65 kA at 480 V, 10 kA at 600 V. Electrical durability: 40,000 cycles at 440 V at half rated current, 20,000 cycles at full rated current, 15,000 cycles at 690 V at half current, 7,500 cycles at 690 V full current. Mechanical durability matches at 40,000 cycles. Power dissipation per pole is 13.95 W — account for 42 W three-phase heat in the enclosure.
