The interrupting ratings are 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That 75.6 kA at 415 V is the figure most often needed for European 400 V industrial panels; it tells you this breaker can clear a bolted fault at the main distribution board without upstream fuses needing to open. ## Current derating and ambient temperature The 160 A rating holds flat from 40 °C up to 50 °C ambient. Above that, the continuous current must be derated: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If this breaker lives in a non-air-conditioned enclosure near a furnace line or in a Middle East panel room, that 144 A at 70 °C is the number to use for load planning — not the 160 A nameplate. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth. The width is a standard 3-pole MCCB footprint — 76.2 mm (3 inches) — so it drops into most panel-mounted MCCB bases without re-drilling.","metaTitle":"Siemens 3VA1116-4EF32-0AD0 SENTRON MCCB, 160 A, 3-pole","metaDescription":"Siemens 3VA1116-4EF32-0AD0 SENTRON molded case circuit breaker, 160 A rated continuous current, 3-pole, TM240 release, IP40 front.

The key difference is the frame rating: this unit is 160 A with a TM240 release, while the 3VA1010-4ED32-0AC0 is a lower-current variant. If the panel bus and wiring are sized for 160 A, the swap is mechanical; if the original panel was built for a smaller frame, verify the lug ampacity and cable size before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1116-4EF32-0AD0","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/3VA1116-4EF32-0AD0 when reusing this data.
