The RK1 classification indicates a high-interrupting-capacity fuse with rejection features that prevent installation in lower-rated fuse holders, a critical safety characteristic for panel and disconnect applications. The time-delay design accommodates normal motor inrush currents without nuisance tripping while still providing fast response to sustained overloads and short-circuit faults. Licensed electricians and qualified electrical contractors are the primary installers of this fuse type.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for motor branch circuit protection, service entrance equipment, motor control centers, and feeder circuits where NEC-compliant overcurrent protection is required. The 600-volt rating covers the majority of single-phase and three-phase commercial and light industrial distribution voltages in North American installations. The pack of 5 units supports stocking requirements for maintenance contractors and panel shops handling multiple circuits or keeping spare inventory on hand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e600-volt AC rating covers standard single-phase and three-phase commercial distribution voltages\u003c\/li\u003e\n  \u003cli\u003e70-amp continuous current rating for motor and feeder circuit protection\u003c\/li\u003e\n  \u003cli\u003eClass RK1 rejection design prevents installation in non-RK1 fuse holders, enforcing circuit integrity\u003c\/li\u003e\n  \u003cli\u003eTime-delay characteristic allows motor inrush without nuisance tripping while protecting against sustained overloads\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5 for multi-circuit jobs and maintenance stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Class RK1 fuse holders and rejection-style fusible disconnects and panelboards rated for 600 volts and 70 amps or greater.

De-energize and lock out the circuit at the upstream overcurrent device before opening any fusible disconnect or panel. Verify the fuse holder is rated for Class RK1 fuses and rated at or above 600 volts and 70 amps before installation. Never install a fuse with a higher ampere rating than the circuit or equipment nameplate requires.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 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\u003eFuse Type\u003c\/strong\u003e: Time-Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 8.000 inches x 6.660 inches x 1.380 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.410 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200199207\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: A6D70R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383842341170,"sku":"A6D70R","price":232.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678684.jpg?v=1782609186","url":"https:\/\/voomisupply.com\/products\/merit-brass-a6d70r-600v-class-rk1-time-delay-fuse-70a-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
