Part of the A25X AMP-TRAP series, it is designed to protect power semiconductors including diodes, phase-control SCRs, and similar power semiconductor devices used in heavy-duty rectifiers and high-power supply circuits. The fuse features a bolt-in blade terminal configuration, a 100 kiloampere (AC) interrupting rating, and a built-in blown-fuse indication. Electricians and power electronics technicians working on industrial drive and rectifier equipment rely on this fuse class for fast, reliable overcurrent protection of semiconductor components.\u003c\/p\u003e\n\u003cp\u003eThe a25x35-4 is intended for industrial applications requiring the protection of heavy-duty rectifiers and similar heavy power supplies. Typical installation scenarios include motor drive panels, power conversion equipment, and industrial control systems where semiconductor devices must be protected from damaging fault currents. The fast-acting characteristic ensures the fuse responds quickly enough to protect sensitive semiconductor junctions before thermal damage occurs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFast-acting semiconductor fuse type engineered for SCR, diode, and power semiconductor protection\u003c\/li\u003e\n  \u003cli\u003e35 ampere current rating at 250 VAC\u003c\/li\u003e\n  \u003cli\u003e100 kiloampere (AC) interrupting rating for high fault-current environments\u003c\/li\u003e\n  \u003cli\u003eBolt-in blade terminal type for secure, low-resistance panel mounting\u003c\/li\u003e\n  \u003cli\u003eBuilt-in blown-fuse indication for quick visual fault identification\u003c\/li\u003e\n  \u003cli\u003eUL listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for the A25X series semiconductor fuse family, intended for use in heavy-duty rectifier protection and similar heavy power supply applications requiring a 35-ampere, 250 VAC fast-acting semiconductor fuse.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing the fuse. Verify the panel and fuse holder accept the bolt-in blade terminal style and confirm the voltage and current ratings match the circuit requirements before installation. Do not substitute a standard time-delay or general-purpose fuse in applications requiring semiconductor-rated fuses.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 35 amperes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 100 kiloampere (AC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharacteristics\u003c\/strong\u003e: Fast Acting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Round, Semiconductor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Blades, Bolt-In\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndication Type\u003c\/strong\u003e: Blown-Fuse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A25X\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: a25x35-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51268653383986,"sku":"A25X35-4","price":231.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912167.jpg?v=1780704842","url":"https:\/\/voomisupply.com\/products\/mersen-a25x35-4-semiconductor-fuse-35a-250vac","provider":"Voomi Supply","version":"1.0","type":"link"}
