The interrupting capacity is the headline: 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. Those numbers define where this breaker can sit in a fault-current study — it handles high available fault current at the lower voltages common in North American distribution, and still carries solid interrupting at 415 V for IEC installations. This is a line-protection design (not motor protection), so it's sized for feeder or main breaker duty. The ground-fault monitoring variant uses summation current formation on the L-conductor — it detects residual current by summing the phase currents, which is typical for solidly-grounded systems where you need GF trip coordination downstream. The breaker measures 138 mm wide by 248 mm tall by 110 mm deep. That 110 mm depth is the front-to-back dimension behind the panel door — important for gland-plate clearance and whether it fits a shallow enclosure. ## Installation environment Maximum power loss is 162 W — that's the heat it dumps into the enclosure at full rated current, so factor that into your thermal budget if the panel is sealed or has limited ventilation. No undervoltage release, no communication function, no voltage trip — this is a straight thermal-magnetic or electronic-trip breaker without add-on modules.","metaTitle":"Siemens 3VA2463-6HM32-0AA0 SENTRON MCCB, 630 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-6HM32-0AA0 molded case circuit breaker, 630 A continuous, 242 kA interrupting at 240 V.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price."},{"question":"What is the closest functional second-source to the 3VA2463-6HM32-0AA0?","answer":"The closest peer is the 3VA2163-8HM32-0AA0 — same SENTRON series, same 3-pole 630 A frame, but with different trip-unit electronics and interrupting ratings. The 3VA2463 carries higher interrupting capacity (242 kA vs lower on the 2163 variant). Drop-in fit depends on the trip curve and fault-current study; the physical footprint is the same, so it mounts in the same panel space without rewiring."},{"question":"Will the 3VA2463-6HM32-0AA0 drop into a panel specified around the 3VA2163-8HM32-0AA0 without rewiring?","answer":"Yes, the physical dimensions are identical — same 138 mm width, 248 mm height, 110 mm depth. The mounting hole pattern and bus-bar spacing are common across the 3VA2 frame. No rewiring needed for the mechanical fit, but verify the trip-unit settings and interrupting rating match your fault-current study before swapping."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a SENTRON molded case circuit breaker, it carries IEC 60947-2 certification and UL 489 listing. Siemens provides RoHS and REACH declarations on request through the standard documentation portal. The 800 V rated insulation voltage aligns with IEC 60947-2 overvoltage category requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2463-6HM32-0AA0","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/3VA2463-6HM32-0AA0 when reusing this data.
