It's built for line protection — meaning it sits upstream protecting a feeder or distribution bus, not a specific motor or drive load. The 220 kA breaking capacity at 240 V tells you this breaker can interrupt a massive fault without welding its contacts or blowing apart; at 415 V it still handles 154 kA, and even at 690 V it holds 17 kA.
At 55 °C it derates to 30.72 A, and at 70 °C — the top of its operating range — it's at 28.8 A.
Auxiliary contacts and shunt trip
That's enough for a remote status indication — say, a PLC input for 'breaker closed' and another for 'breaker tripped' — plus a spare for something else. The shunt trip (STL) release is built in, so you can trip the breaker remotely via a control signal.
