Its breaking capacity drops from 242 kA at 240 V to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and 9 kA at 690 V — so the voltage class of your distribution system determines which fault level this breaker can safely interrupt. ## Auxiliary Switch Complement and Undervoltage Release The UVR ensures the breaker drops out on loss of control voltage — standard practice for safety circuits where a voltage dip must open the main contacts. The HQ designation on the alarm switch means it provides a separate signal path for remote indication, not just a shared common. Panel builders should account for the wiring terminations of all five switches in the enclosure layout. ## Active Production — Current Lifecycle Status The 3VA2463-6HN32-0CL0 carries a lifecycle stage of 'current', meaning Siemens continues to manufacture and support this order code as an active catalog item. No last-time-buy or phase-out notice applies. For BOM-freeze planning, this part is a standard-line item with no imminent replacement pressure. ## Thermal Derating — Current vs. Ambient Temperature Above that, the continuous current derates linearly: 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.","metaTitle":"Siemens 3VA2463-6HN32-0CL0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens 3VA2463-6HN32-0CL0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 242 kA at 240 V.
