The interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V — that SCCR lets it ride through high-fault scenarios without cascading upstream breakers. At 415 V this MCCB clears 187 kA, and at 500 V it still handles 121 kA. Those numbers mean the breaker can be used in high-capacity switchboards where fault current runs high — think large motor control centers or transformer secondaries. The 690 V rating drops to 3 kA, so it's not the right choice for 690 V systems with high fault potential; that's a selectivity coordination call the panel designer has to make. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA footprint that drops into a DIN-rail or screw-mounted enclosure without panel modifications. ## Temperature derating and power loss The 25 A rating holds flat from 40 °C all the way to 70 °C — no derating curve to calculate for warm enclosures.","metaTitle":"Siemens 3VA2025-6KQ36-0AA0 SENTRON MCCB, 25 A, 3-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2025-6KQ36-0AA0 molded case circuit breaker, 25 A continuous, 3-pole, 242 kA at 240 V.

It is quoted to order against an RFQ; availability and current pricing are confirmed at quote time. Volume pricing drops with quantity — tell me how many you want and I'll get you a friend price."},{"question":"When sourcing 3VA2025-6KQ36-0AA0, what's the closest functional second-source?","answer":"The closest functional sibling is the 3VA2125-8KQ42-0AA0. Both are 3-pole SENTRON MCCBs with communication, but the 3VA2125 carries a higher continuous current (125 A vs 25 A). They share the same frame size and mounting footprint, so panel cutouts and bus connections are identical — no rewiring needed for a swap if the load current allows."},{"question":"What is 3VA2025-6KQ36-0AA0's listed depth (86 mm) on this component line?","answer":"The depth is 86 mm (3.39 in). That's the dimension from the mounting surface to the front of the breaker — important for enclosure depth clearance."},{"question":"What is 3VA2025-6KQ36-0AA0's listed width (105 mm) on this component line?","answer":"The width is 105 mm (4.13 in). That's the pole-to-pole dimension across the three poles — standard for this SENTRON frame."},{"question":"Will 3VA2025-6KQ36-0AA0 drop into a panel that was specified around 3VA2125-8KQ42-0AA0 without rewiring?","answer":"Yes, the two breakers share the same physical footprint — 105 mm wide, 181 mm tall, 86 mm deep — and the same SENTRON frame. The bus connections and DIN-rail mounting are identical, so a direct swap is possible as long as the load current is within the 25 A rating of this MCCB."},{"question":"What compliance documentation does this brand provide for 3VA2025-6KQ36-0AA0 (RoHS, REACH, UL, IEC)?","answer":"As a Siemens SENTRON product, this MCCB is designed to meet IEC 60947-2 and relevant UL standards for molded case circuit breakers. RoHS and REACH compliance declarations are standard from the manufacturer. Specific certificates (UL file, CE declaration) are available on request with the order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2025-6KQ36-0AA0","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/3VA2025-6KQ36-0AA0 when reusing this data.
