The breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. The shunt trip means a control signal (from an E-stop, PLC, or fire-alarm relay) can open the breaker remotely, which is the usual integration point in a safety circuit.
Thermal derating — the real-world current limit
Above that, it derates: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
No auxiliary switch is fitted (design of auxiliary switch: without), so if you need status feedback to a PLC, you'll add a separate auxiliary switch block.
