Its dual-element design tolerates brief startup surges while the time-delay characteristic minimizes nuisance trips for motors and power supplies. The device is non-indicating with ferrule end terminals and measures about 1.06 in diameter by 5.5 in long. It carries an interrupting rating of 200 kA at 600 VAC and 20 kA at 250 VDC, making it suitable for branch-circuit protection in higher-energy systems. As part of the FRS-R family, it aligns with the energy-efficient Fusetron protection, designed for use in Class RK5 fuse holders. Typical applications include HVAC equipment and motor circuits in industrial controls and power-distribution panels where reliable 600 VAC protection is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"BUSSMANN","offers":[{"title":"New","offer_id":51677536256302,"sku":null,"price":53.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c98c0e1e-33c8-4512-949f-75a126e130c6.jpg?v=1769564274","url":"https:\/\/plgautomation.com\/products\/bussmann-frs-r-45-dual-element-time-delay-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
