At 40 °C it handles 200 A continuous without derating; that figure holds through 50 °C, then steps down to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The breaking capacity is what makes this part stand out in a distribution panel: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The 70 mm depth and 140 mm width fit a standard SENTRON draw-out or fixed-mount chassis, so it drops into an existing 3VA lineup without reworking the bus bars. The auxiliary switch configuration — 1 auxiliary + 1 trip alarm switch HQ — gives you one NO/NC for status feedback and a separate alarm contact that closes only on a trip event, not on manual switching. That's a clean way to signal a fault to a PLC without ladder logic to distinguish a manual off from a protective trip.
Mounts in a standard SENTRON draw-out cradle or fixed-mount base. The 140 mm width occupies four 35 mm DIN spaces if using the DIN-rail adapter; verify the specific mounting kit for your panel.
