Above that it derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your enclosure sits near a motor drive or in a hot machine room, size the breaker for the actual ambient, not the nameplate. ## Breaking capacity across voltage — selectivity planning This MCCB's interrupting rating drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. ## Physical fit and accessory layout The breaker measures 70 mm deep by 76.2 mm wide by 130 mm tall — standard 3-pole MCCB footprint for a 100 A frame. The basic switch variant is 3VA11105EF320AA0. Lifecycle status is marked as current — Siemens still builds this exact order code. No last-time-buy clock ticking, no broker scramble. If you need a functional second-source, the 3VA1110-5ED36-0AC0 is the closest peer in the same frame size but with different trip settings — verify your coordination study before swapping.","metaTitle":"Siemens 3VA1110-5EF32-0HH0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens 3VA1110-5EF32-0HH0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, 187 kA breaking capacity at 240 V.

Submit a request for current pricing and availability — we confirm both at quote time."},{"question":"When sourcing 3VA1110-5EF32-0HH0, what's the closest functional second-source — 3VA1110-5ED36-0AC0?","answer":"The 3VA1110-5ED36-0AC0 is the closest peer in the same 3VA frame size and 3-pole count, but it carries different trip settings. Verify your selective coordination study before substituting — the two are not drop-in interchangeable without recalculating the trip curve."},{"question":"What is 3VA1110-5EF32-0HH0's listed depth (70 mm) on this component line?","answer":"The listed depth is 70 mm (2.76 in). Combined with a 76.2 mm width and 130 mm height, it fits standard 3-pole MCCB panel cutouts for a 100 A frame."},{"question":"Will 3VA1110-5EF32-0HH0 drop into a panel that was specified around 3VA1110-5ED36-0AC0 without rewiring?","answer":"Mechanically yes — same frame dimensions, same 3-pole layout. But electrically no: the trip settings differ. You must verify the coordination study and adjust the trip unit if needed. The shunt trip and auxiliary switch complement may also differ; check the accessory wiring diagram."},{"question":"What compliance documentation does this brand provide for 3VA1110-5EF32-0HH0 (RoHS, REACH, UL, IEC)?","answer":"As a Siemens SENTRON product, the 3VA1110-5EF32-0HH0 is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers. RoHS and REACH declarations are available from Siemens on request. The 800 V rated insulation voltage confirms IEC compliance for 690 V systems."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-5EF32-0HH0","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/3VA1110-5EF32-0HH0 when reusing this data.
