This non‑indicating cartridge fuse fits standard RK5 holders and offers an interrupting rating up to 200 kAIC at 600 VAC and 20 kAIC at 300 VDC, with a 600 VAC \/ 300 VDC rating and a time‑delay profile that tolerates brief surges without nuisance blows. Marketed as energy‑efficient, the FRS‑R family claims up to about 23% energy savings compared with older designs while maintaining protection performance. UL listed and widely available from major distributors and retailers, including Mouser, Lowe’s, and Walmart, it is a common choice for protecting high‑voltage power distribution equipment and other circuits operating around 600 VAC. With its dual‑element construction, it combines rapid overload response with surge tolerance to help safeguard downstream devices and wiring in industrial and commercial electrical systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Bussmann","offers":[{"title":"New","offer_id":51677539467566,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d16e0425-d280-422f-b15a-c776cd734afb.jpg?v=1769564332","url":"https:\/\/plgautomation.com\/products\/bussmann-frs-r-20-high-voltage-energy-efficient-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
