Class RK1 fuses deliver a high degree of current limitation and are recognized for their precision in protecting motors, transformers, and feeders from both overload and short-circuit conditions. The dual-element, time-delay construction allows temporary inrush currents to pass without nuisance tripping while responding rapidly to sustained faults. Licensed electricians and electrical contractors install this fuse type in industrial, commercial, and residential service panels and disconnect switches.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for applications requiring Class RK1 performance in 250-volt AC circuits. Typical installations include motor branch circuits, HVAC equipment disconnects, feeder circuits, and panelboard protection where high current-limiting capability and selectivity are required. The 70-amp rating makes it appropriate for mid-range motor loads and equipment feeders commonly found in light commercial and industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e250-volt AC rated for standard single-phase and three-phase distribution circuits\u003c\/li\u003e\n  \u003cli\u003e70-amp continuous current rating for mid-range feeder and motor protection\u003c\/li\u003e\n  \u003cli\u003eClass RK1 current-limiting performance for superior fault protection\u003c\/li\u003e\n  \u003cli\u003eTime-delay element accommodates motor starting inrush without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003eRejection-style ferrule ends prevent installation into lower-rated fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class RK1 fuse holders and disconnect switches rated for 250 volts and 70 amps or higher.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing any fuse. Verify that the fuse holder or disconnect is rated for Class RK1 fuses and is sized for at least 70 amps at 250 volts. Never replace a fuse with one of a higher ampere rating than the circuit is designed to carry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 70 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200191519\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A2K70R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383769628978,"sku":"A2K70R","price":343.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677987.jpg?v=1782606903","url":"https:\/\/voomisupply.com\/products\/merit-brass-a2k70r-250v-class-rk1-fuse-70-amp","provider":"Voomi Supply","version":"1.0","type":"link"}
