Any mounting position is permitted, which helps when laying out a dense panel where vertical or horizontal orientation matters for wire routing. Screw-type terminals on the main current circuit accept solid or stranded conductors: 2× (1…2.5 mm²) and 2× (2.5…6 mm²). The IP20 front is standard for enclosed panels; no additional finger-safe shrouding required behind the gland plate. Shock resistance is 25 g / 11 ms, adequate for machine-mounted panels on presses or conveyors. The mechanical endurance of the main contacts is typically 100 000 operations, and the maximum switching frequency at AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1021-0FA10-0FJ0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0FA10-0FJ0 SIRIUS motor protection circuit breaker, 0.5 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V.

However, the 3RV1021-0FA10-0FJ0 carries a 0.5 A continuous rating versus the 3RV1011-0GA10's different rating — verify the motor FLA matches the new breaker's setting range before swapping. The wiring terminal capacity (solid/stranded 1…6 mm²) is identical, so no re-termination is needed if the conductor size is within that range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1021-0FA10-0FJ0","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 when reusing this data.
