Rated 80 A continuously at ambient temperatures from 40 °C to 50 °C, it derates to 74 A at 70 °C — a thermal curve worth checking if the panel sits near a heat source or in a non-climate-controlled enclosure. Breaking capacity is 187 kA at 240 V, stepping down to 121 kA at 415 V and 75.6 kA at 440 V — figures that cover most industrial service-entrance and feeder applications where high fault current is a given. At 500 V and 690 V it still holds 17 kA, so it handles 480 V and 600 V class systems without a separate current-limiting fuse.
The shunt trip lets a safety PLC or emergency-stop circuit drop the breaker remotely; the alarm switch signals a trip event back to the control system.
