That thermal curve means you can size the breaker for a 100 A feeder in a ventilated enclosure and still have headroom if the ambient climbs to 50 °C. The interrupting ratings are the real story here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. ## TM240 release and undervoltage trip — what drives the trip curve The 240 designation refers to the release frame, not the continuous rating; the breaker itself is set for 100 A continuous. An undervoltage release (UVR) is integrated as standard, wired to the auxiliary trip accessory listed as 3VA9608-0BB25. No communication function, no phase-failure detection, no ground-fault monitoring — this is a straight line-protection breaker, not a multifunction power monitor. ## Panel fit — dimensions and mounting The breaker measures 130 mm high, 76.2 mm wide (3-pole width — standard 3-module DIN footprint), and 70 mm deep. The 76.2 mm width matches the 3VA1110 frame across the 3VA family, so a panel laid out for a 3VA1112-5EF32-0CA0 (which is a 125 A frame, different release) shares the same mounting footprint — the 3VA1110-4EF32-0DH0 drops into the same DIN slots without rewiring the bus bars, provided the continuous current and interrupting ratings match the application.","metaTitle":"Siemens 3VA1110-4EF32-0DH0 SENTRON MCCB, 100 A, 121 kA at 24","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0DH0 molded case circuit breaker, 3-pole, 100 A continuous, 121 kA at 240 V.

The 3VA1110-4EF32-0DH0 is a 100 A frame with a TM240 release; the 3VA1112 is a 125 A frame. They share the same mounting footprint (76.2 mm width, 130 mm height, 70 mm depth), so the 3VA1110-4EF32-0DH0 drops into a panel laid out for the 3VA1112 without rewiring the bus bars, provided the 100 A rating and TM240 release match the application."},{"question":"What is 3VA1110-4EF32-0DH0's listed depth (70 mm) on this component line?","answer":"The depth is 70 mm, measured from the mounting surface to the rear of the breaker body. This fits a standard 200 mm deep enclosure with room for wiring gutters."},{"question":"What is 3VA1110-4EF32-0DH0's listed width (76.2 mm) on this component line?","answer":"The width is 76.2 mm for the 3-pole version, which is the standard 3-module DIN footprint. This matches the 3VA1110 frame across the SENTRON 3VA family."},{"question":"Will 3VA1110-4EF32-0DH0 drop into a panel that was specified around 3VA1112-5EF32-0CA0 without rewiring?","answer":"Yes, the two breakers share the same mounting footprint — 76.2 mm width, 130 mm height, 70 mm depth. The 3VA1110-4EF32-0DH0 snaps into the same DIN slots and accepts the same bus-bar connections, provided the 100 A continuous rating and TM240 release match the application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-4EF32-0DH0","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/3VA1110-4EF32-0DH0 when reusing this data.
