Breaking capacity is a key specification for this class: the unit delivers 50 kA at 400 V AC and 240 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC. For audit purposes, the screw-type terminals on the main circuit accept 2× (1 to 25 mm²) or 1× (1 to 35 mm²) solid or stranded copper, requiring a Pozidriv size 2 screwdriver tip with a 5 to 6 mm shaft diameter. ## Protection Features and Backup Fusing The breaker includes phase failure detection, which is critical for preventing single-phasing damage on three-phase motor loads. It does not include ground fault detection. For installations where the prospective short-circuit current exceeds the breaker's rated breaking capacity, the datasheet specifies required backup fuses: at 400 V, a gG 125 A fuse; at 500 V, gG 100 A; at 690 V, gG 80 A. At 240 V, no backup fuse is required.","metaTitle":"Siemens 3RV2031-4EA10-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2031-4EA10-0BA0 motor protection circuit breaker, size S2, Class 10 trip, 50 kA breaking capacity at 400 V AC.

The S2 frame carries higher breaking capacities and a larger terminal cross-section. A direct drop-in replacement without panel modifications is not possible due to the width difference."},{"question":"Will 3RV2031-4EA10-0BA0 drop into a panel specified around 3RV2023-4DA10?","answer":"No, the 3RV2031-4EA10-0BA0 is a size S2 frame at 55 mm width, while the 3RV2023-4DA10 is a size S0 frame at 45 mm width. The 10 mm width increase means the DIN rail mounting footprint is different, and terminal positions may not align without panel rework."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV2031-4EA10-0BA0","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/3RV2031-4EA10-0BA0 when reusing this data.
