The interrupting ratings are voltage-dependent: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — per the datasheet, these are the maximum fault currents the breaker can safely clear at each voltage level. ## Thermal Derating and Power Dissipation The continuous current rating derates with rising ambient temperature inside the enclosure: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Maximum power loss is 162 W at rated load — this figure matters for panel thermal calculations, especially when grouping multiple breakers in a sealed cabinet. ## Physical Dimensions and Mounting Depth of 110 mm includes the case body; allow additional clearance for rear terminals and wiring bends. ## Integrated Shunt Trip and Communication The breaker also supports communication functions (per the product designation), enabling integration with higher-level monitoring systems for status and trip data. The undervoltage release is not fitted on this order code.","metaTitle":"Siemens 3VA2463-6JQ32-0JA0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0JA0 molded case circuit breaker, 630 A at 40 °C, 3-pole, line protection.
