Built under the Amp-Trap 2000 product line, this fuse features time-delay characteristics that allow it to ride through harmless inrush and transient overloads without nuisance opening, while still providing fast, reliable short-circuit protection. The cylindrical body measures 10.75 inches in length and 4.5 inches in diameter, with blade-style terminal connections. It carries UL E2137\/238 and CSA C22.2 listings. Electricians and electrical contractors install this fuse in high-ampacity service entrance, feeder, and distribution panel applications where current-limiting Class L protection is required by the NEC.\u003c\/p\u003e\n\u003cp\u003eThe a4bq2500 is suited for a wide range of industrial and commercial electrical applications. Typical use cases include main service protection, feeder circuits, large motor branch circuits, lighting and heating loads, general load protection, circuit breaker back-up duty, UPS systems, and battery circuit protection. The time-delay design makes it especially well suited for motor circuits that draw significant inrush current on startup. The GMG body material and tin-plated copper contacts are designed for mounting in Class L clip-style fuse holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2500-amp continuous current rating at 600 volts AC and 500 volts DC\u003c\/li\u003e\n  \u003cli\u003eTime-delay characteristics tolerate motor inrush and transient overloads without nuisance blowing\u003c\/li\u003e\n  \u003cli\u003eHigh interrupting capacity: 200 kiloamps AC and 100 kiloamps DC\u003c\/li\u003e\n  \u003cli\u003eBlade terminal type for secure seating in Class L clip-style holders\u003c\/li\u003e\n  \u003cli\u003eGMG body with tin-plated copper contacts for reliable conductivity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eUL E2137\/238 and CSA C22.2 listed for use in North American electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Class L fuse holders that accept clip-mounted blade terminal fuses.

De-energize and verify absence of voltage on the circuit before handling or replacing this fuse. Use Class L-rated fuse clips and pull tools sized for the fuse body dimensions. Never replace a current-limiting fuse with a non-current-limiting type or a fuse of a higher ampere rating than the circuit requires.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 2500 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts AC, 500 volts DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 200 kiloamps (AC), 100 kiloamps (DC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTime-Delay Characteristics\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Cylindrical Rejection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: GMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Material\u003c\/strong\u003e: Tin-Plated Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Clip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL E2137\/238, CSA C22.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200193013\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: a4bq2500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51268215177522,"sku":"A4BQ2500","price":5293.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912293.jpg?v=1780701873","url":"https:\/\/voomisupply.com\/products\/mersen-a4bq2500-class-l-time-delay-fuse-2500a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
