The interrupting capacity derates with voltage: 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V, so verify your system's available fault current at the point of installation against the appropriate voltage column. Rated continuous current Iu is 630 A, but that's at 40 °C ambient. The breaker derates linearly as cabinet temperature rises: 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. ## Trip unit, auxiliary contacts, and shunt trip — what's on board This breaker ships with the ETU320 electronic overcurrent release — a basic line-protection trip unit (no ground fault, no communication, no phase failure detection). There is no undervoltage release on this variant. The breaker also includes a voltage trigger and a trip indicator (mechanical flag), so a blown fuse or tripped breaker is visible on the front face without opening the panel door. ## Physical fit — dimensions and mounting Dimensions are 248 mm height × 138 mm width × 110 mm depth. ## Environmental limits and mechanical endurance Mechanical endurance (latching cycles) is rated at 15,000 operations — adequate for a main breaker or feeder breaker that sees infrequent switching, not for a motor-starting duty cycle.","metaTitle":"Siemens 3VA2463-5HL32-0HL0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5HL32-0HL0 molded case circuit breaker, 630 A rated, 187 kA interrupting at 240 V. 3-pole, line protection, ETU320 release.
