Class L fuses in this ampere range are bolt-in style and built to handle the high inrush currents common in large motor loads, transformers, and service entrance equipment. The time-delay characteristic allows temporary overload conditions to pass without nuisance opening while still providing fast response to fault-level currents. Licensed electricians and electrical contractors are the primary installers of this fuse class.\u003c\/p\u003e\n\u003cp\u003eThe A4BT2000 is suited for use in heavy industrial facilities, commercial buildings, and utility service sections where high-ampacity branch circuit and feeder protection is required. Typical applications include motor control centers, large air handling unit feeders, main service disconnects, and transformer secondary protection. Its 600-volt rating covers the full range of standard North American three-phase distribution voltages including 480-volt and 600-volt systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2000-amp continuous current rating for high-capacity feeder and service protection\u003c\/li\u003e\n  \u003cli\u003e600-volt AC rating covers standard 480V and 600V three-phase systems\u003c\/li\u003e\n  \u003cli\u003eClass L form factor with bolt-in termination for secure, low-resistance connections\u003c\/li\u003e\n  \u003cli\u003eTime-delay design tolerates motor inrush and transformer magnetizing currents without nuisance opening\u003c\/li\u003e\n  \u003cli\u003eCurrent-limiting construction reduces incident energy and protects downstream equipment during fault conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-stock Class L fuse for industrial and commercial electrical panelboards, switchgear, and disconnect switches rated for Class L fuse elements at 2000 amps and 600 volts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) Article 240 and local electrical codes. De-energize and lock out the circuit at the upstream disconnect before servicing or replacing fuses. Verify that the fuse holder or disconnect is rated for Class L fuses at the required ampacity and voltage before installation. Do not substitute a lower time-delay or non-current-limiting fuse type in applications where Class L is specified by the equipment manufacturer or design engineer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 2000A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResponse Type\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200193998\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: A4BT2000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51383451713842,"sku":"A4BT2000","price":2713.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678174.jpg?v=1782597061","url":"https:\/\/voomisupply.com\/products\/mersen-a4bt2000-class-l-time-delay-fuse-2000a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
