The interrupting capacity is 187 kA at 240 V AC, stepping down to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V — figures that govern selectivity coordination downstream. The 63 A rating holds flat from 40 °C through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C; if the panel ambient runs above 50 °C, size the upstream feeder for the derated value, not the nameplate.
The 3VA1163-5GE46-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 4-pole width (101.6 mm) is the critical dimension for DIN-rail or mounting-plate space — verify the existing panel layout has that slot free. In a densely packed enclosure, that heat must be factored into the thermal budget.
Compliance documentation for this series covers RoHS, REACH, and the relevant IEC/UL standards for molded case circuit breakers.
