The A-release (thermal overload) is adjustable from 2.2 to 3.2 A, and the short-circuit release is fixed at 42 A. This combination means the device provides both overload and short-circuit protection for a motor or feeder in that current band — the 42 A magnetic trip clears a fault before the thermal element can overheat, while the 2.2–3.2 A range lets you dial in the full-load current of the connected load. Termination is via screw terminals, and the unit carries standard switching capacity for typical industrial panel duty. RoHS compliant since October 1, 2009, and REACH Article 33 candidate-list information is available from Siemens.","metaTitle":"Siemens 3RV2021-1DA10-0DA0 SIRIUS 3RV2 Motor Starter Protect","metaDescription":"Siemens 3RV2021-1DA10-0DA0 SIRIUS 3RV2 motor starter protector, size S0, A-release 2.2-3.2 A, short-circuit release 42 A, screw terminal, RoHS compliant, active production, availab","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Protection Circuit Breakers (MPCB)"],"specifications":{"title":"3RV2021-1DA10-0DA0","Group Code":"R711","description":"circuit breaker size S0 for system protection without phase failure protection A-release 2.2...3.2 A short-circuit release 42 A screw terminal standard switching capacity","Product Group":"5333","Product class":"A: Standard product which is a stock item could be returned within the returns guidelines/period.","Quantity Unit":"1 Piece","Product Family":"SIRIUS 3RV2 motor starter protectors","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : EAR99","Packaging dimensions (L x W x H)":"102.00 x 49.00 x 102.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-10-09","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/90c40dec14ff7b214e2ab6809a69ab64.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RV2021-1DA10-0DA0?tree=CatalogTree"},"ai":{"faq":[{"question":"What is the overload and short-circuit protection range for this part?","answer":"The A-release (thermal overload) is adjustable from 2.2 to 3.2 A, and the short-circuit release is fixed at 42 A.
