Time-delay fuses in the RK1 class are engineered to withstand temporary inrush currents common in motor loads and HVAC compressor circuits while still providing reliable overcurrent protection. This fuse arrives in a 5-pack configuration, making it practical for service vans and shop stock. Electricians and HVAC technicians install this type of fuse in fusible disconnect switches, load centers, and equipment service disconnects where motor loads require a fuse that will not nuisance-trip on startup.\u003c\/p\u003e\u003cp\u003eThe A2D90R is suited for residential and light commercial electrical applications where an RK1-class time-delay fuse is specified. Common install scenarios include HVAC condensing unit disconnects, compressor panels, and motor-driven equipment that draws significant startup current. The 5-per-pack quantity supports multi-unit service calls or stocking requirements at a shop or supply house. Packaged dimensions are 6.000 inches by 5.380 inches by 1.060 inches, with a total pack weight of 1.630 pounds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-amp rating suitable for large motor and compressor circuit protection\u003c\/li\u003e\n\u003cli\u003e250-volt rating for single-phase and compatible multi-phase circuits\u003c\/li\u003e\n\u003cli\u003eRK1 class designation provides high interrupting capacity and rejection feature to prevent misapplication\u003c\/li\u003e\n\u003cli\u003eTime-delay design tolerates motor inrush without nuisance opening\u003c\/li\u003e\n\u003cli\u003eSold in a 5-pack for stocking and multi-unit service efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for RK1-class time-delay fuses in fusible disconnects and overcurrent protection equipment rated for 90 amps at 250 volts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the disconnect or panel before removing or installing fuses. Verify that the fuse holder or disconnect is rated for RK1-class fuses before installation, as RK1 fuses require a rejection-style holder. Never replace a fuse with a higher amperage rating than the circuit is designed to carry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 90 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 250 volts\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 (TD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 6.000 inches x 5.380 inches x 1.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.630 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200199100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: A2D90R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383339548978,"sku":"A2D90R","price":137.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678623.jpg?v=1782593800","url":"https:\/\/voomisupply.com\/products\/merit-brass-a2d90r-time-delay-fuse-90a-250v-rk1-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
