At 690 V the interrupting rating drops to 9 kA, so this breaker is not suited for 690 V distribution unless the available fault current is known to be under that threshold. The continuous current derates with ambient temperature: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. If the panel ambient runs above 40 °C, the actual load must be reduced accordingly — a 630 A pump motor in a 50 °C enclosure would need the 593 A derated limit, not the nameplate 630 A. That means it detects residual current by summing the phase currents — useful for equipment protection in grounded systems, though it is not a personnel-protection GFCI. Breaker measures 138 mm wide by 248 mm high by 110 mm deep. Maximum power loss is 162 W at rated current. That heat must be considered in the enclosure thermal calculation — a sealed cabinet with no forced ventilation will need to be sized to dissipate that loss without exceeding the 70 °C maximum operating temperature.","metaTitle":"Siemens 3VA2463-7HM32-0AA0 SENTRON MCCB, 630 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2463-7HM32-0AA0 molded case circuit breaker, 630 A continuous, 3-pole, 330 kA interrupting at 240 V.
