It carries a maximum interrupt capacity of 480 A, with breaking capacities of 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V — so the same breaker handles different fault-current levels across common industrial voltages without swapping frames.
Thermal performance across the panel ambient range
That simplifies panel thermal budgeting: you don't have to oversize the breaker for a 50 °C switchroom or a cabinet sitting next to a drive.
Built-in communication and ground-fault monitoring
That saves an external ground-fault relay in panels where earth-leakage detection is required.
