Its interrupting capacity hits 187 kA at 240 V and 121 kA at both 415 V and 440 V, dropping to 75.6 kA at 500 V and 9 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries where the available short-circuit current is substantial. The breaker includes a built-in communication function, which means it can report status and trip events to a PLC or BMS without an add-on module.
The continuous current rating is temperature-dependent: 630 A at 40 °C, stepping down to 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.
Auxiliary switching and trip indication
The trip indicator is present on the front face, so a walk-by inspection catches a tripped breaker without opening the panel door.
