The interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and still holds 52.5 kA at 690 V — so it handles high-fault industrial feeds without cascading upstream.
The 63 A frame keeps the footprint compact enough for a 600 mm wide enclosure with room for a downstream contactor and overload relay in a motor starter column.
Thermal derating — what the 63 A rating actually delivers
Above that it starts to taper: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
The 4 HQ auxiliary switches (form C) are integrated into the breaker; the basic switch module is order code 3VA2163-7MS32-0AA0, and the auxiliary trip module is 3VA9608-0BB24. No phase-failure detection or voltage trigger on this variant.
