The 57S 150% overload capability is the key selection parameter: it defines how long the drive can sustain a 50% current surge above its base rating. For a motor driving a loaded conveyor start or a pump with a high breakaway torque, that 57-second window covers the acceleration ramp without tripping. If your application requires sustained overload beyond 57 seconds, you would need to step up to a higher base-rated module in the S120 family.","metaTitle":"Siemens 6SL3520-1XA20-3AF0 SINAMICS S120 Drive, 57S 150%","metaDescription":"Siemens 6SL3520-1XA20-3AF0 SINAMICS S120 drive module, rated 57S 150% overload.

This covers the acceleration ramp for high-inertia loads like conveyors, crushers, or centrifuges without nuisance tripping. If your load requires overload beyond 57 seconds, select a higher base-rated S120 module."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6SL3520-1XA20-3AF0","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/6SL3520-1XA20-3AF0 when reusing this data.
