{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3VA2463-6JQ42-0AA0","brand":"Siemens","brandSlug":"siemens","productSlug":"3VA2463-6JQ42-0AA0","canonicalUrl":"https://aoctrl.com/siemens/3VA2463-6JQ42-0AA0","factsUrl":"https://aoctrl.com/api/mcp/products/3VA2463-6JQ42-0AA0","rawCanonicalId":null},"summary":{"shortDescription":"Siemens SENTRON 3VA2463-6JQ42-0AA0, molded case circuit breaker, 4-pole, 630 A continuous, adjustable I²t trip 945-5670 A, SCCR 242 kA at 240 V, line protection design with communication function.","salesMarkdown":"## Siemens 3VA2463-6JQ42-0AA0 — 630 A SENTRON MCCB, 4-Pole, Adjustable Trip, High SCCR The Siemens 3VA2463-6JQ42-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a 4-pole configuration and an adjustable I²t trip unit covering 945 A to 5 670 A. The SCCR curve is the deciding factor for fault-current coordination: 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. ## Thermal Derating — Continuous Current vs. Ambient Temperature Per the datasheet, derate linearly: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Plan the load at the derated value for the expected enclosure temperature. ## Lifecycle and Sourcing — Current Production, Quoted to Order The lifecycle stage is current production. This is an active catalog line from Siemens SENTRON, not a phase-out or NRND part. ## Dimensions and Panel Fit — 110 mm Depth, 184 mm Width, 248 mm Height The 3VA2463-6JQ42-0AA0 measures 110 mm deep, 184 mm wide, and 248 mm tall. The 184 mm width (7.24 in) is the critical dimension for DIN-rail or mounting-plate spacing — it occupies roughly 7.25 inches of rail width. The 110 mm depth (4.33 in) leaves clearance for rear-access wiring in a standard 600 mm deep enclosure. Verify gland-plate clearance for the line and load conductors at the 630 A rating, which typically requires multiple conductors per phase. ## Ground-Fault and Communication — Summation Current Sensing, Communication Function Present The ground-fault monitoring uses summation current formation on the L + N conductors, meaning it measures vector sum of phase and neutral currents to detect leakage. The communication function is present (yes), which on the 3VA2 platform typically supports PROFIBUS or PROFINET via a communication module — useful for remote trip indication, energy monitoring, and selective coordination in a networked distribution system. ## Power Loss and Operating Limits Maximum power loss is 162 W at rated current — relevant for enclosure thermal calculations, especially when multiple breakers are ganged.","metaTitle":"Siemens 3VA2463-6JQ42-0AA0 SENTRON MCCB, 630 A, 4-Pole, 242","metaDescription":"Siemens 3VA2463-6JQ42-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 4-pole, adjustable I²t trip 945-5670 A, SCCR 242 kA at 240 V.

The 3VA2463 carries a higher continuous current rating (630 A vs. the peer's rating) and a different trip-unit adjustment range. Verify the specific trip curve and SCCR requirements before substituting — the frame size and pole count are the same, but the internal trip calibration differs."},{"question":"What is the depth of 3VA2463-6JQ42-0AA0?","answer":"The depth is 110 mm (4.33 in)."},{"question":"What is the width of 3VA2463-6JQ42-0AA0?","answer":"The width is 184 mm (7.24 in)."},{"question":"Will 3VA2463-6JQ42-0AA0 drop into a panel specified around 3VA2063-8JQ42-0AA0 without rewiring?","answer":"Both are 4-pole SENTRON 3VA2 frame breakers with the same physical dimensions (110 mm depth, 184 mm width, 248 mm height), so the mechanical fit is identical. However, the 3VA2463 is rated for 630 A continuous versus the peer's lower rating, and the trip-unit adjustment range differs. The line and load conductors must be sized for 630 A — if the existing panel was wired for a lower ampacity, rewiring is required."},{"question":"What compliance documentation does Siemens provide for 3VA2463-6JQ42-0AA0?","answer":"As a SENTRON MCCB, it carries IEC 60947-2 certification.
