This Bussmann FRN-R-30 is a 30-amp, 250-volt Class RK5 dual-element fuse for motor control centers, panelboards, starters, machinery disconnects, pumps, air-conditioning equipment and other correctly designed circuits.\u003c\/p\u003e\u003cp\u003eThe current-limiting fuse is UL listed and CSA certified, measures 2 x 0.56 x 0.56 inches and uses a fiberglass tube with brass end caps. The delay is listed at a minimum of ten seconds at 500% rated current, while severe short-circuit conditions can open the dual element much faster. Replacement must match the equipment class, voltage, ampere rating and interrupting requirements. De-energize, verify and follow qualified electrical service procedures.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: Bussmann\u003c\/li\u003e\n\u003cli\u003eProduct: Dual-element time-delay cartridge fuse\u003c\/li\u003e\n\u003cli\u003eSeries: Fusetron FRN\u003c\/li\u003e\n\u003cli\u003eModel: BP-FRN-R-30\u003c\/li\u003e\n\u003cli\u003eCatalog number: FRN-R-30\u003c\/li\u003e\n\u003cli\u003eCurrent rating: 30A\u003c\/li\u003e\n\u003cli\u003eVoltage rating: 250V\u003c\/li\u003e\n\u003cli\u003eFuse class: RK5\u003c\/li\u003e\n\u003cli\u003eAction: Time delay\u003c\/li\u003e\n\u003cli\u003eElements: Dual element\u003c\/li\u003e\n\u003cli\u003eCurrent limiting: Yes\u003c\/li\u003e\n\u003cli\u003eDimensions: 2 x 0.56 x 0.56 inches\u003c\/li\u003e\n\u003cli\u003eTube: Fiberglass\u003c\/li\u003e\n\u003cli\u003eEnd caps: Brass\u003c\/li\u003e\n\u003cli\u003eCertifications: UL listed and CSA certified\u003c\/li\u003e\n\u003cli\u003ePack quantity: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003csection class=\"product-faq\"\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhat circuits use an FRN-R-30 fuse?\u003c\/h3\u003e\n\u003cp\u003eIt is intended for compatible 30A 250V Class RK5 motor and branch circuits designed for a dual-element time-delay fuse.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhy does the fuse have a time delay?\u003c\/h3\u003e\n\u003cp\u003eThe delay allows typical temporary motor-starting current while still opening during sustained overload or short-circuit conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eCan I replace it with any 30A cartridge fuse?\u003c\/h3\u003e\n\u003cp\u003eNo. Fuse class voltage interrupting rating dimensions and equipment requirements must all match.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhat should be done before replacement?\u003c\/h3\u003e\n\u003cp\u003eDe-energize and verify the circuit and use qualified electrical service procedures and protective equipment.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"My Store","offers":[{"title":"Default","offer_id":64470905454961,"sku":"B00004WA2X","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/7064\/0241\/files\/71DsBf2PDKL._SL1500.jpg?v=1787906866","url":"https:\/\/allkindora.shop\/products\/bussmann-frn-r-30-amp-brass-250-volt-fusetron-dual-element-time-delay-rk5-cartridge-fuse","provider":"All Kindora","version":"1.0","type":"link"}
