The 33 A magnetic instantaneous trip handles the inrush without nuisance tripping on start, then clears a bolted fault fast enough to limit let-through energy to downstream contactors. Termination is screw-type, standard switching capacity, and the unit ships in multi-unit packaging (12 pieces per pack). Frame size S0 fits the SIRIUS common mounting rail and bus system, so it integrates directly with 3RT2 contactors and 3RU2 thermal overloads in the same panel footprint — no adapter brackets needed. RoHS compliant since 1 October 2009. This is standard for electrical terminals and solder joints; the declaration supports your downstream REACH communication obligations.","metaTitle":"Siemens 3RV2021-1CA10-Z W97 SIRIUS Motor Protector, 1.8-2.5","metaDescription":"Siemens 3RV2021-1CA10-Z W97 SIRIUS 3RV2 motor starter protector, frame size S0, Class 10, 1.8-2.5 A thermal, 33 A magnetic.

The '-Z W97' denotes a special version (often multi-unit packaging or a specific customer variant). The standard single-unit version shares the same electrical ratings (Class 10, 1.8–2.5 A thermal, 33 A magnetic) and the same S0 frame footprint.

REACH Article 33 duty to inform applies: the part contains lead (CAS 7439-92-1) above 0.1% w/w. No UL or IEC certification numbers are listed in the available documentation, but the SIRIUS 3RV2 series typically carries IEC/EN 60947-4-1 and UL 508 listing — verify the specific certification marking on the nameplate if your application requires it."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV2021-1CA10-Z-W97","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/3RV2021-1CA10-Z-W97 when reusing this data.
