The basic switch variant is 3VA2440-7HL32-0AA0, meaning this order code adds the undervoltage release to that base unit. ## Integration and physical fit These dimensions match the standard SENTRON 3VA frame footprint for 400 A breakers. Panel cutout and mounting-hole pattern are consistent across the series, so a panel designed for a 3VA2 frame accepts this unit without modification. Maximum power loss is 66 W — account for that heat load in the enclosure thermal calculation, especially when grouping multiple breakers. The minimum breaking capacity is 600 A, which is the lowest fault current the breaker can reliably interrupt. The 400 A continuous rating at 70 °C ambient means no derating in warm enclosures, a real advantage in packed panels or outdoor cabinets exposed to solar gain.","metaTitle":"Siemens 3VA2440-7HL32-0BA0 SENTRON MCCB, 400 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0BA0 molded case circuit breaker, 400 A rated, 3-pole, 330 kA breaking capacity at 240 V.
