The breaker measures 86 mm deep, 140 mm wide, and 181 mm tall — that's a standard 4-pole MCCB footprint for a 63 A frame. It's designed for screw-mounting in a distribution panel or enclosure. The interrupting rating drops as voltage rises: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Power loss is 3 W maximum — negligible for panel thermal budgeting. The ETU350 release is the electronic trip unit with LSI protection (long-time, short-time, instantaneous).","metaTitle":"3VA2063-8HN46-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU350, 440 k","metaDescription":"Siemens SENTRON 3VA2063-8HN46-0AA0 molded case circuit breaker. 63 A continuous, 4-pole, ETU350 release, 440 kA breaking at 240 V.

Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here."},{"question":"What is the closest functional alternative to 3VA2063-8HN46-0AA0?","answer":"The 3VA2063-8JQ42-0AA0 is a close functional sibling — same 63 A frame and 4-pole count, but with a different trip unit or accessory set. The physical footprint (86 mm depth, 140 mm width, 181 mm height) is identical, so it drops into the same panel cutout without rewiring. The deciding factor is the overcurrent release: the -8HN46-0AA0 carries the ETU350 electronic release, while the -8JQ42-0AA0 uses a different release variant. Check your coordination study before swapping."},{"question":"What is the depth of 3VA2063-8HN46-0AA0?","answer":"The depth is 86 mm (3.39 in). That's the dimension from the mounting surface to the front of the breaker body, not including any handle projection."},{"question":"What is the width of 3VA2063-8HN46-0AA0?","answer":"The width is 140 mm (5.51 in), which is standard for a 4-pole 63 A MCCB frame in the SENTRON 3VA series."},{"question":"Will 3VA2063-8HN46-0AA0 drop into a panel specified around 3VA2063-8JQ42-0AA0?","answer":"Yes, the physical dimensions are identical — same 86 mm depth, 140 mm width, 181 mm height — so it fits the same panel cutout and bus bar spacing without rewiring. The difference is in the trip unit: the -8HN46-0AA0 uses an ETU350 electronic release, while the -8JQ42-0AA0 has a different release. Verify your trip settings and selectivity coordination before swapping."},{"question":"What compliance documentation is available for this breaker?","answer":"As a Siemens SENTRON product, this MCCB is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers. RoHS and REACH compliance documentation is typically included in the manufacturer's declaration package. Specific certs (UL, CSA, CE) should be confirmed against the nameplate marking on the unit you receive."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2063-8HN46-0AA0","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/3VA2063-8HN46-0AA0 when reusing this data.
