It provides thermal‑magnetic motor protection with a Class 10 A‑release setting of 1.1–1.6 A and a 21 A short‑circuit release, using screw terminals and a 220–690 VAC rating to suit small to medium motors. In practical terms, it can protect motors up to about 0.55 kW in typical 220–690 VAC applications; Siemens notes this model is no longer available and the recommended successor is 3RV2011-1AA10, making it appropriate to consider the newer device for updated availability and compatibility in legacy panel designs.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268128133354,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3rv1021-1aa10-molded-case-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
