Its interrupting ratings step down cleanly from 187 kA at 240 V to 121 kA at 415 V, then 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — so the 415 V figure is the one to check against your transformer secondary or bus fault current. Current-carrying capacity holds at 200 A from 40 °C through 50 °C ambient, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Maximum power loss is 42 W.
Panel fit and mechanical integration
Dimensions: 158 mm height, 140 mm width, 70 mm depth. The 4-pole body is wider than a 3-pole equivalent — check your DIN-rail or mounting-plate space before committing the panel layout.
