It uses a Class 10 overload release with an adjustable current setting in the 18–25 A range (nominally 25 A) and provides short-circuit protection rated to 325 A, with 6 kV impulse withstand and IP20 front protection. The device employs spring-type terminals and can be augmented with an optional auxiliary contact via a product extension, with standard switching capacity for motor protection across a 220–690 VAC supply (typical installations around 11 kW).\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268136620266,"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-3rv2021-4da10-motor-protection-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
