That 63 A holds flat through 50 °C and only starts to taper at 55 °C — 62 A — dropping to 58 A at 70 °C, so you get full rating in most ventilated enclosures without derating. Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V, which covers the high-fault end of most industrial distribution boards. Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a 4-pole MCCB that fits standard panel-mount cutouts for the SENTRON 3VA frame. The 70 mm depth leaves room behind the door for wiring and auxiliary wiring without crowding. That means you get remote status (open/closed/tripped) and undervoltage protection without adding separate accessories. No ground-fault monitoring version on this variant. Maximum power loss is 19.8 W — plan for that in the enclosure thermal budget.","metaTitle":"Siemens 3VA1063-2ED42-0DH0 SENTRON MCCB, 63A, 4-Pole, 52.5kA","metaDescription":"Siemens SENTRON 3VA1063-2ED42-0DH0 molded case circuit breaker, 63A rated at 40°C, 4-pole, breaking capacity 52.5kA at 240V.

The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time — no stock count or price is published here."},{"question":"What is the breaking capacity of 3VA1063-2ED42-0DH0 at different voltages?","answer":"Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.

The 3VA1063-2ED42-0DH0 is rated 63 A versus the 3VA1010's lower rating, so verify the upstream protection and cable sizing — but the panel cutout and mounting holes match."},{"question":"What compliance documentation does Siemens provide for 3VA1063-2ED42-0DH0?","answer":"As a standard SENTRON MCCB, it carries CE marking for the European market and is designed to meet IEC 60947-2. UL and CSA listings are typical for the 3VA series, but confirm the specific certification for your jurisdiction at order time. RoHS and REACH declarations are available from Siemens documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1063-2ED42-0DH0","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/3VA1063-2ED42-0DH0 when reusing this data.
