The interrupting ratings are serious: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and still 5 kA at 690 V. That means it handles high-fault-current scenarios without cascading upstream — useful when you're feeding a panel off a large transformer or a utility service with stiff source impedance.
Built-in shunt trip and auxiliary contacts
The two auxiliary switches give you status feedback (open/closed) without needing an add-on block. No undervoltage release, no communication module, no phase-failure detection on this build — it's a straightforward remote-trip + status package for a distribution panel or motor control center.
Above that it derates linearly: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C — the maximum operating temperature. Physical dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard SENTRON 3VA2 footprint, so it drops into the same mounting base and bus-bar system as other 3VA2 frame sizes.
