The S2 frame footprint is 55 mm wide, 140 mm tall, 149 mm deep — plan for that depth behind the panel door. Clearance requirements: 50 mm above and below, 30 mm to the side, 140 mm forward; zero clearance needed behind the rail. Screw-type box terminals on top and bottom accept up to 35 mm² solid or 25 mm² fine-stranded with ferrules; torque to 3–4.5 N·m. ## Electrical Ratings and Environment Rated for 690 V maximum (AC-3), 50/60 Hz, with a surge voltage resistance of 6 kV. Total typical power loss is 12 W. Relative humidity tolerance is 10 to 95 %. Shock resistance per IEC 60068-2-27 is 25 g for 11 ms. Maximum installation altitude is 2000 m above sea level. Maximum operating frequency in AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV5031-4DA10 SIRIUS Motor Protection CB, 25 A, Clas","metaDescription":"Siemens 3RV5031-4DA10 SIRIUS motor protection circuit breaker, 25 A rated, AC-3 at 400 V, Trip Class 10, 3-pole, S2 frame, 690 V max, screw terminals, DIN rail mount.

The key difference is the frame size — 3RV5031-4DA10 is an S2 frame, while 3RV6021-4DA10 is an S0 frame. The S0 frame is physically smaller (45 mm wide vs 55 mm), so a panel cut out for the S2 will have extra width if you swap to the S0. Both are 3-pole, Class 10, and use screw terminals, but verify the current rating and terminal wire range on the specific variant before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV5031-4DA10","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/3RV5031-4DA10 when reusing this data.
