Rated 75.6 kA at 240 V and 52.5 kA at 415 V, it clears high-fault conditions without cascading upstream, which matters when you're coordinating selectivity in a panel feeding multiple downstream breakers. Three poles, 800 V insulation rating, and an undervoltage release (UVR) built in as the auxiliary release type — that UVR lets you drop the breaker on a control signal or safety circuit, useful for emergency-stop chains or undervoltage protection on a machine feeder.
Above that, it derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, down to 45 A at 70 °C.
