Short-circuit breaking capacity is 100 kA at 400 V AC — the same rating holds at 240 V, 500 V, and 690 V AC. That's a full-range 100 kA rating, not a derated curve. The 45 mm width takes one standard module slot. Depth is 96 mm, height 97 mm. Terminals are screw-type for the main circuit, accepting 2x (1 to 2.5 mm²) solid or stranded, or 2x (2.5 to 6 mm²). AWG equivalents are 2x (14 to 10). No auxiliary contacts are included — if you need a remote trip signal, you'll add the separate auxiliary switch block (confirms it's compatible). Shock resistance is 25 g for 11 ms. Mounting position is any.","metaTitle":"Siemens 3RV1021-0FA10-0FJ0-ZX95 SIRIUS Motor Protection Circ","metaDescription":"Siemens SIRIUS 3RV1021-0FA10-0FJ0-ZX95 motor protection circuit breaker, 0.5 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V AC.

However, the 3RV1021 series has a different terminal layout and internal construction than the 3RV1011 series — verify the terminal positions and wiring access against your panel layout before assuming a drop-in swap. The screw-type terminals accept the same wire ranges (2x 1 to 2.5 mm² solid or stranded, or 2x 2.5 to 6 mm²), so rewiring the same conductors is possible if the terminal positions align."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1021-0FA10-0FJ0-ZX95","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/3RV1021-0FA10-0FJ0-ZX95 when reusing this data.
