Class RK1 fuses provide a high degree of current limitation, making them well suited for protecting motors, transformers, panelboards, and service-entrance equipment where both overload and short-circuit protection are required. The time-delay characteristic allows the fuse to ride through normal motor-inrush currents without nuisance opening, while still providing fast response to dangerous fault conditions. Licensed electricians and industrial maintenance technicians are the primary installers of this class of overcurrent protective device.\u003c\/p\u003e\n\u003cp\u003eClass RK1 fuses are used in residential, commercial, and industrial applications wherever the National Electrical Code requires a current-limiting overcurrent protective device. The A2K600R is appropriate for motor branch circuits, feeder circuits, and service entrances rated up to 250 volts AC. The RK1 rejection feature prevents installation in a lower-rated fuse holder, enforcing the correct interrupting rating at the panel or disconnect.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e600-amp continuous current rating for high-capacity branch and feeder circuits\u003c\/li\u003e\n  \u003cli\u003e250-volt AC voltage rating suitable for single-phase and three-phase systems\u003c\/li\u003e\n  \u003cli\u003eClass RK1 current-limiting design for superior short-circuit protection\u003c\/li\u003e\n  \u003cli\u003eTime-delay action accommodates motor-inrush and transformer-magnetizing currents\u003c\/li\u003e\n  \u003cli\u003eRK1 rejection feature prevents installation in non-RK1 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 disconnects rated 600 amps at 250 volts AC.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lockout\/tagout the circuit and verify absence of voltage before handling any fuse or fuse holder. Use properly rated fuse pullers when removing or inserting high-amperage fuses. Verify that the fuse holder is listed for Class RK1 devices and is rated for the circuit voltage and amperage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 600 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200191541\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: MERSEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A2K600R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51383079174450,"sku":"A2K600R","price":1599.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678012.jpg?v=1782587457","url":"https:\/\/voomisupply.com\/products\/mersen-a2k600r-600a-250v-rk1-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
