It provides a continuous current rating of 16 A, a mechanical life of about 100,000 switching cycles, and an auxiliary contact arrangement of 1 NO + 1 NC. The device includes screw terminals and a short‑circuit release rated at 208 A, with standard switching capacity that accommodates a transverse auxiliary switch. It offers IP20 front protection, and a surge‑voltage withstand of up to 6,000 V, making it suitable for machine control where transient high voltages may be encountered. The unit is specified for operation up to 2,000 m above sea level. Siemens notes this model as a legacy product no longer available, with the recommended successor in the current lineup being 3RV2021-4AA15. This makes it a compact motor‑protection option for compact panels, where a dedicated motor protector with integrated auxiliary contacts and screw‑terminal connections is appropriate.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268129214698,"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-3rv1021-4aa15-molded-case-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
