The interrupting ratings tell you where it can clear a fault without welding or bursting: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — so it handles high available fault current on the secondary side of a large transformer or in a heavy industrial feeder. This breaker carries a shunt trip release (STL) and two factory-fitted auxiliary switches (HQ) — so it can be remotely tripped by a safety circuit or PLC and gives status feedback.
