What this 630 A MCCB does on the line
Thermal derating is published across the full operating range: 630 A at 40 °C drops to 450 A at 70 °C. That means remote tripping and status feedback are wired from the factory — no field retrofit of the shunt trip coil.
The 3VA2463-6JP32-0JH0 measures 248 mm high by 138 mm wide by 110 mm deep.
Breaking capacity at system voltages
Breaking capacity is voltage-dependent and published per IEC/UL: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. The 690 V figure is notably lower — if the breaker is used on a 690 V IT system or a wind turbine collector, the available fault current must be verified against that 9 kA limit.
