Any mounting position is allowed, so vertical or horizontal rail orientation works. ## Fuse backup and ratings For applications requiring a backup fuse upstream, the maximum permitted gL/gG fuse rating is 32 A at 400 V and 500 V, dropping to 25 A at 690 V. The maximum switching frequency in AC-3 duty is 15 operations per hour.","metaTitle":"Siemens SIRIUS 3RV2011-1FA40 Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV2011-1FA40 motor protection circuit breaker.

The 3RV2011-1FA40 offers a higher 100 kA breaking capacity at 400 V compared to the 3RV1011 series, which typically maxes out at lower SCCR ratings. Panel fit (45 mm width, DIN rail) is the same, but the interrupting rating difference means the 3RV2011 is specified for higher-fault installations."},{"question":"What is 3RV2011-1FA40's listed depth (97 mm) on this component line?","answer":"The listed depth is 97 mm."},{"question":"What is 3RV2011-1FA40's listed width (45 mm) on this component line?","answer":"The listed width is 45 mm."},{"question":"Will 3RV2011-1FA40 drop into a panel that was specified around 3RV1011-1HA10 without rewiring?","answer":"Both parts share the same 45 mm width and DIN rail mounting, so the physical footprint is identical. However, the 3RV2011-1FA40 has a higher 100 kA breaking capacity, so the upstream protective device coordination may need review — the panel's fault current rating must support the higher SCCR."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV2011-1FA40","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/3RV2011-1FA40 when reusing this data.
