The interrupting ratings step down cleanly across voltage tiers: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. Above that, derate in roughly 2–3% steps per 5 °C: 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. If your panel internal ambient runs at 50 °C — common in a packed enclosure with drives — you lose about 6% of the headline ampacity. The mechanical endurance of 15,000 operations is typical for a fixed-mounted MCCB used as a main disconnect; it's not designed for frequent switching like a contactor. The ETU320 release offers LSI protection (long-time, short-time, instantaneous) with adjustable pickups — no ground-fault or communication functions on this variant. Phase failure detection is not built in; that's handled upstream or by the motor protection relay.","metaTitle":"Siemens 3VA2463-5HL32-0CA0 SENTRON MCCB, 630A, 3-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2463-5HL32-0CA0 molded case circuit breaker, 630A rated current, 3-pole, ETU320 release, 187 kA at 240 V.

The 3VA2463 frame is the 630 A tier; the 3VA1112 tops out at lower current. They share the same DIN-rail mounting pattern, but the 3VA1112 won't carry 630 A — verify your load before substituting."},{"question":"Will 3VA2463-5HL32-0CA0 drop into a panel specified around 3VA1112-5EF32-0CA0 without rewiring?","answer":"No. The 3VA2463 frame is physically larger (248 x 138 x 110 mm vs the smaller 3VA1112 frame). The busbar spacing and lug positions differ. You'll need to rework the mounting and bus connections. Stick with the 3VA2463 if your BOM calls for 630 A."},{"question":"What compliance documentation is available for 3VA2463-5HL32-0CA0?","answer":"Siemens SENTRON MCCBs carry IEC 60947-2 certification as standard. RoHS and REACH declarations are available from the manufacturer. UL/CSA listing depends on the specific variant — the -0CA0 suffix with UVR may not carry UL file numbers; verify with the factory if UL listing is required for your jurisdiction."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2463-5HL32-0CA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2463-5HL32-0CA0 when reusing this data.
