That interrupting rating places it squarely in high-fault main-breaker duty — think transformer secondaries, large motor control centers, or service-entrance panels where available fault current exceeds what a standard 65 kA or 100 kA breaker can handle. The 630 A frame carries a continuous current derating curve from 630 A at 40 °C down to 520 A at 70 °C, so panel ambient temperature directly affects the usable ampacity. ## Line protection with integrated shunt trip The basic switch platform is order code 3VA2463-7HN32-0AA0, so the -0JC0 suffix adds the shunt trip and aux switches as a pre-assembled option rather than field-installed accessories. Dimensions are 110 mm deep, 138 mm wide, and 248 mm tall. The 138 mm width (5.43 in) is a 3-pole frame size that occupies three adjacent 45 mm module positions on a DIN rail or panel-mount busbar system. Maximum power loss is 162 W at rated current, so ventilation or derating within the enclosure must account for that heat dissipation — particularly in sealed, high-ambient cabinets. ## Interrupting capacity across voltage levels The breaker's interrupting capacity varies significantly with system voltage: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. For 400 V class systems (common in European and Asian industrial plants), the 242 kA rating provides generous headroom for most main-breaker positions.","metaTitle":"SENTRON 3VA2463-7HN32-0JC0 MCCB, 630 A, 3-Pole, 330 kA","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0JC0 molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 330 kA interrupting at 240 V.
