630 A MCCB with 242 kA interrupting capacity
Its interrupting capacity hits 242 kA at 240 V, stepping down to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V — that's a fault-current envelope that covers most industrial service-entrance and large-feeder applications without needing a current-limiting fuse upstream. The ETU560 electronic trip unit handles the protection curve, and the built-in undervoltage release (UVR) lets you drop the breaker on a control signal or safety circuit.
Above that, derate in 10 °C steps: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C.
