The 220 kA interrupting rating at 240 V AC means it can clear a bolted fault at that level without the arc flashing upstream; at 415 V and 440 V it still holds 154 kA, and at 690 V it drops to 17 kA. ## Derating and thermal reality At 55 °C it derates to 488 A, at 60 °C to 476 A, at 65 °C to 464 A, and at 70 °C to 452 A. Maximum power loss is 122.7 W — that heat has to leave the enclosure, so factor it into your panel thermal calculation. Dimensions: 184 mm wide, 248 mm tall, 110 mm deep. Four-pole frame, so it occupies the full width of a standard MCC bucket or a 600 mm wide enclosure section. Rated insulation voltage 800 V. Mounts with the standard SENTRON screw-clamp kit — verify the bus-bar adapter if you're feeding from a common bus.","metaTitle":"Siemens 3VA1450-6GF42-0AA0 SENTRON MCCB, 500 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1450-6GF42-0AA0 molded case circuit breaker, 500 A, 4-pole, 220 kA at 240 V.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead-time commitment."},{"question":"What is the closest functional second-source to 3VA1450-6GF42-0AA0?","answer":"The peer MPNs 5SQ2670-2YA63, 5SQ2670-2YA16, and 5SQ2670-0KA15 are listed as alternates. Verify the interrupting rating and release type against your coordination study before substituting — the 3VA1450 carries 220 kA at 240 V and 154 kA at 415 V, which may exceed the peer's SCCR."},{"question":"What is the depth of 3VA1450-6GF42-0AA0?","answer":"110 mm (4.33 in).

Physical interchange is not guaranteed without checking the Siemens mounting template — the 184 mm width matches the standard SENTRON footprint, but verify the lug kit and terminal orientation against your existing bus."},{"question":"What compliance documentation does Siemens provide for 3VA1450-6GF42-0AA0?","answer":"As a SENTRON MCCB, it carries CE marking for the European market and is designed to meet IEC 60947-2. RoHS and REACH declarations are standard from Siemens for this series. UL/CSA listing depends on the specific variant — confirm with the manufacturer's declaration for your region."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1450-6GF42-0AA0","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/3VA1450-6GF42-0AA0 when reusing this data.
