Dual element fuses\nfeature separate overload and short-circuit elements to provide the same short\ncircuit protection as a fast acting fuse with the added benefit of letting\ninrush currents pass without opening the fuse. As a time-delay fuse, it allows\nfor temporary overload conditions without opening (sometimes called blowing a\nfuse). This is necessary for equipment that regularly experiences short-term\npower surges, such as when a motor or transformer strarts up. The time-delay\nfeature allows an inrush current from the motor or transformer to start\nwithout opening but still protects against sustained overloads and short\ncircuits. This also allows you to reduce the need to replace expired due to\nnormal inrush overloads. For superior electrical protection, we recommend\nupgrading to Bussmann series Low-Peak LPS-RK fuses. From the Manufacturer\nHeavy duty time-delay fuse used in motor protection. When sized correctly, it\nhelps protect motors from burnout caused by overloads or single-phasing. The\ntime-delay feature allows the initial startup current surge for typical motors\nto pass, but opens prior to motor burnout when longer, dangerous overloads are\npresent. In addition, the dual-element design opens in as little as 0.004\nsecond if the fuse experiences short-circuit conditions. UL Listed Class R\n(IR: 200kA). Groove in end cap or notch in knife blade permit the fuse to be\nused in Class H, Class K or Class R fuse blocks. Cartridge fuses are used to\nprotect motors and branch circuits where higher amps or volt ratings are\nrequired. They are available in a wide variety of sizes, amp and volt ratings\nup to 600Vac and 600 amps. Cartridge fuses are used extensively in commercial,\nindustrial and agricultural applications as well as residential fuse panels,\nair conditioning, pumps, appliances and other equipment. Cartridge fuses are\navailable in two types. General Purpose fuses have no time-delay and protect\nfuse panels, appliances and branch circuits. Heavy- Duty fuses have a time-\ndelay feature, allowing momentary motor startups. Both are available in 250Vac\nand 600Vac versions with catalog symbol and amp rating stamped on the knife\nblade or end cap.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eThe Bussmann series FRS-R-35 is an energy effcient, dual-element, time-delay Class RK5 fuse and is part of our FUSETRON line of fuses.\u003c\/li\u003e\n \u003cli\u003eIts dual-element design provides the best time-delay for better protection of equipment such as power panelboards, combination starters, motor control centers, machinery disconnects, and safety switches.\u003c\/li\u003e\n \u003cli\u003eDual element fuses feature separate overload and short-circuit elements to provide the same short circuit protection as a fast acting fuse with the added benefit of letting inrush currents pass without opening the fuse.\u003c\/li\u003e\n \u003cli\u003eAs a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse).\u003c\/li\u003e\n \u003cli\u003eThis is necessary for equipment that regularly experiences short-term power surges, such as when a motor or transformer strarts up.\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-07-30T17:35:14+10:00","created_at":"2026-07-27T00:20:30+10:00","vendor":"Bussmann","type":"Cartridge Fuses","tags":["home_improvement_Aug2026"],"price":14500,"price_min":14500,"price_max":14500,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":48068619206807,"title":"1","option1":"1","option2":null,"option3":null,"sku":"B005273BTS","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Eaton Bussmann FRS-R-35 Class RK5 Fuse, Time-delay Dual-element Current Limiting, 35 A, Interrupting Rating of 200 kA at 600 Vac and 20 kA at 250 Vdc 1 - 1","public_title":"1","options":["1"],"price":14500,"weight":132,"compare_at_price":null,"inventory_management":"shopify","barcode":"051712508353","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/newnestshop.com\/cdn\/shop\/files\/B005273BTS.jpg?v=1785075632","\/\/newnestshop.com\/cdn\/shop\/files\/41oJf5ousKL.jpg?v=1785075632","\/\/newnestshop.com\/cdn\/shop\/files\/31qZPZ58YHL.jpg?v=1785075632","\/\/newnestshop.com\/cdn\/shop\/files\/31Oaktpu9LL.jpg?v=1785075632"],"featured_image":"\/\/newnestshop.com\/cdn\/shop\/files\/B005273BTS.jpg?v=1785075632","options":["Number of Items"],"media":[{"alt":null,"id":42460671115415,"position":1,"preview_image":{"aspect_ratio":1.0,"height":1000,"width":1000,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/B005273BTS.jpg?v=1785075632"},"aspect_ratio":1.0,"height":1000,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/B005273BTS.jpg?v=1785075632","width":1000},{"alt":null,"id":42460671148183,"position":2,"preview_image":{"aspect_ratio":1.0,"height":600,"width":600,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/41oJf5ousKL.jpg?v=1785075632"},"aspect_ratio":1.0,"height":600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/41oJf5ousKL.jpg?v=1785075632","width":600},{"alt":null,"id":42460671180951,"position":3,"preview_image":{"aspect_ratio":1.0,"height":600,"width":600,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/31qZPZ58YHL.jpg?v=1785075632"},"aspect_ratio":1.0,"height":600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/31qZPZ58YHL.jpg?v=1785075632","width":600},{"alt":null,"id":42460671213719,"position":4,"preview_image":{"aspect_ratio":1.0,"height":600,"width":600,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/31Oaktpu9LL.jpg?v=1785075632"},"aspect_ratio":1.0,"height":600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/31Oaktpu9LL.jpg?v=1785075632","width":600}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eEaton Bussmann FRS-R-35 Class RK5 Fuse, Time-delay Dual-element Current Limiting, 35 A, Interrupting Rating of 200 kA at 600 Vac and 20 kA at 250 Vdc\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThe Bussmann series FRS-R-35 is an energy effcient, dual-\nelement, time-delay Class RK5 fuse and is part of our FUSETRON line of fuses.\nIts dual-element design provides the best time-delay for better protection of\nequipment such as power panelboards, combination starters, motor control\ncenters, machinery disconnects, and safety switches.
