That is the threshold where the breaker opens on a hard fault without waiting for thermal overload — critical for limiting let-through energy to downstream contactors and cables. For a 16 A motor full-load current, 208 A is roughly 13x In, which is a typical magnetic-only setting for motor starting inrush (DOL start can pull 6–8x FLA for a few cycles). If your motor has a higher inrush or a soft-start profile, check coordination; this breaker is not adjustable. The 12 W typical power loss matters for enclosure thermal rise — in a sealed panel with multiple breakers, that heat adds up. The S2 size footprint is 55 mm wide, 140 mm high, 149 mm deep. Clearance requirements: 50 mm above, 50 mm below, 30 mm to the side, 140 mm forward. No clearance needed behind the rail. Accepts 2x 0.75–25 mm² or 1x 0.75–35 mm² solid/stranded wire at the screw-type box terminals. Torque range 3–4.5 N·m. Mounting position any.","metaTitle":"Siemens 3RV5331-4AC10 SIRIUS Circuit Breaker, 16 A AC-3, 690","metaDescription":"Siemens 3RV5331-4AC10 SIRIUS circuit breaker for starter combinations. 16 A AC-3 at 400 V, 690 V rated, 208 A instantaneous trip.

Availability and current pricing are confirmed at quote time against an RFQ — submit one for a firm lead time."},{"question":"What is the closest functional second-source to 3RV5331-4AC10?","answer":"The 3RV5341-4LC10 is a higher-current sibling in the same SIRIUS S2 family. It shares the same physical footprint and DIN rail mount, but its AC-3 rating at 400 V is higher — verify your load current before substituting. The 3RV5331-4AC10 is the 16 A variant; the 3RV5341-4LC10 steps up to a larger rating. If your BOM calls for 16 A, the 3RV5331-4AC10 is the correct fit."},{"question":"Will 3RV5331-4AC10 drop into a panel specified for 3RV5341-4LC10 without rewiring?","answer":"Physically yes — same S2 size, same DIN rail mount, same terminal arrangement. But the 3RV5341-4LC10 is rated for a higher current. If the panel wiring and downstream components are sized for that higher current, dropping in the 16 A 3RV5331-4AC10 will work as long as the load is within 16 A. If the load exceeds 16 A, the breaker will trip on overload. Verify the motor FLA before swapping."},{"question":"What compliance documentation does Siemens provide for 3RV5331-4AC10?","answer":"The part carries a substance prohibitance date of 07/01/2006, indicating RoHS compliance from that date. The rated insulation voltage of 690 V and surge voltage resistance of 6 kV align with IEC 60947-2 requirements. For specific UL, CSA, or CE declarations, request the manufacturer's declaration of conformity with your RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV5331-4AC10","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/3RV5331-4AC10 when reusing this data.
