{"product_id":"industrial-frs-r-40-nsnbc01-fuse","title":"Industrial FRS-R-40 NSNBC01 Fuse","description":"\u003cdiv\u003e\u003cp\u003eThe Bussmann\/Eaton Fusetron FRS-R-40 is a Class RK5, dual‑element time‑delay fuse rated for 40 A, designed for industrial control panels, power distribution, and equipment protection in machines and drives. It supports a 600 VAC and 300 VDC rating, providing current‑limiting protection for motors, transformers, power supplies, and other high‑inrush loads, with interrupting ratings up to 200 kA at 600 VAC and 20 kA at the DC rating (250–300 VDC depending on exact variant). The device is non‑indicating, with an optional open‑fuse indication available on select ratings, and is listed to UL 248‑12 with CE and CSA certifications, reflecting wide acceptance in electrical safety standards. In practice, FRS-R‑40 variants are commonly used in industrial equipment housings, control cabinets, and electrical distribution blocks where reliable time‑delay protection against short overloads is needed without false trips during inrush. Some listings refer to the model with suffixes such as NSNBC01, but the core specification remains a 40 A Fusetron RK5 time‑delay fuse suitable for 600 VAC\/300 VDC circuits and high‑fault‑current environments. \u003c\/p\u003e\u003c\/div\u003e","brand":"BUSSMANN","offers":[{"title":"New","offer_id":51677538386222,"sku":null,"price":28.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8c32e404-534f-439e-8360-e768663ec15a.jpg?v=1769564318","url":"https:\/\/plgautomation.com\/products\/industrial-frs-r-40-nsnbc01-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
