This is a line-protection device, meaning it is designed for main feeder or large distribution applications where high fault current capability is required to maintain selectivity downstream. ## Thermal derating and power dissipation This matters for panel layout — if the breaker is enclosed with other heat sources, the actual ampacity may be lower than the nameplate. Maximum power loss is 162 W, which must be considered in the enclosure thermal budget. ## Integrated shunt trip release The undervoltage release is not fitted on this order code. If undervoltage protection is required, specify a different variant or add an external relay. Dimensions are 248 mm height, 138 mm width, 110 mm depth. The width is the critical dimension for multi-pole grouping in a panel — three poles fit in a 138 mm wide footprint.","metaTitle":"Siemens 3VA2463-7HN32-0JA0 SENTRON MCCB, 630 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0JA0 molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 330 kA breaking at 240 V.
