Its interrupting capacity hits 220 kA at 240 V, dropping to 154 kA at 415 V and 121 kA at 440 V — still substantial headroom for most industrial service-entrance or feeder applications. The TM240 thermal-magnetic release handles overload and short-circuit response without external power. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint for panel-mounting on a DIN rail or direct screw fixing. ## Thermal derating and ambient range Full 63 A rating holds through 50 °C; at 55 °C it drops to 62 A, at 60 °C to 61 A, and at 65 °C to 60 A. At 70 °C ambient you're at 58 A. If your panel sits near a furnace or in a hot attic, use the 60 °C or 65 °C row for sizing.","metaTitle":"Siemens 3VA1163-6EF32-0AG0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens 3VA1163-6EF32-0AG0 SENTRON molded case circuit breaker, 3-pole, 63 A rated at 40 °C, 220 kA interrupting at 240 V.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price."},{"question":"What is the interrupting capacity at different voltages?","answer":"At 240 V it's rated 220 kA; at 415 V it's 154 kA; at 440 V it's 121 kA; at 500 V and 690 V it holds 17 kA. Use the 240 V figure for low-voltage fault duty and the 415 V figure for 400 V class systems."},{"question":"Will 3VA1163-6EF32-0AG0 drop into a panel specified for 3VA1110-5ED36-0AC0?","answer":"No — the 3VA1110-5ED36-0AC0 is a different frame size and current rating. The 3VA1163-6EF32-0AG0 is a 63 A, 3-pole MCCB with a TM240 release; the 3VA1110 is a smaller 10 A unit. The physical footprint and mounting pattern differ, so a panel cutout and bus work designed for the 10 A breaker will not accept this 63 A breaker without modification."},{"question":"What compliance documentation does this breaker carry?","answer":"As a Siemens SENTRON product, it carries CE marking for the European market and meets applicable IEC/EN 60947-2 standards for molded case circuit breakers. RoHS and REACH declarations are available from Siemens. Specific UL/CSA listings vary by variant — confirm with the datasheet for your jurisdiction."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-6EF32-0AG0","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/3VA1163-6EF32-0AG0 when reusing this data.
