As a key component in electrical distribution, this fuse is suitable for use by electrical distributors and switchgear suppliers requiring reliable current-limiting protection with coordination for ground fault relays. The A4BY fuse supports continuous currents up to its ampere rating and features a 4-second minimum time delay at 500% rating to allow normal current surges to pass without nuisance interruptions.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAmperage Rating: 601 A\u003c\/li\u003e\n  \u003cli\u003eVoltage Rating: 600 VAC, 300 VDC\u003c\/li\u003e\n  \u003cli\u003eInterrupt Rating: 200 kA\u003c\/li\u003e\n  \u003cli\u003eFuse Class: Class L\u003c\/li\u003e\n  \u003cli\u003eDimensions (L x W x H): 8.63 in x 2 in x 2 in\u003c\/li\u003e\n  \u003cli\u003eMounting Type: Bolted\u003c\/li\u003e\n  \u003cli\u003eConnection: Blade\u003c\/li\u003e\n  \u003cli\u003eInsulation Material: GMG\u003c\/li\u003e\n  \u003cli\u003eProduct Weight: 3.64 lbs\u003c\/li\u003e\n  \u003cli\u003eManufacturer: Mersen\u003c\/li\u003e\n  \u003cli\u003eManufacturer Part #: A4BY601\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCurrent-limiting design to reduce fault energy and improve system protection\u003c\/li\u003e\n  \u003cli\u003e4-second time delay at 500% rating for coordination with ground fault relays and to pass normal surges\u003c\/li\u003e\n  \u003cli\u003eGlass melamine body and plated terminals for superior reliability in harsh environments\u003c\/li\u003e\n  \u003cli\u003eUnique dimensions prevent replacement by other fuse classes, ensuring proper fit and safety\u003c\/li\u003e\n  \u003cli\u003eBlade stamped catalog numbers for permanent identification\u003c\/li\u003e\n  \u003cli\u003eUL and CSA listed to applicable standards for safety and performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDownloads \u0026amp; Links\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/mersen\/2021q1\/documents\/31b2b1e7ac269488134aff9115ae3dd4e809ed5b.pdf?did=4169\u0026amp;pid=403501\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSpec Sheet\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/mersen\/2021q1\/documents\/1a7554e25913a5959d6828cae9cecdf365babb61.pdf?did=4169\u0026amp;pid=403501\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCurves 1\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/mersen\/2021q1\/documents\/a5b3c1e6f8908bd7378bcf99ccdb3a686d284cfe.pdf?did=4169\u0026amp;pid=403501\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSpec Sheet FR\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/mersen\/2021q1\/documents\/1a2f877f363cb973a53a58e7151167469ddba921.pdf?did=4169\u0026amp;pid=403501\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCurves 2\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/mersen\/2021q1\/documents\/afdf70a5520664d0bf2eb75f5cd65eed3f05879c.pdf?did=4169\u0026amp;pid=403501\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDrawings\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mersen","offers":[{"title":"Default Title","offer_id":46092401017057,"sku":"194842","price":616.43,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/9625\/4433\/files\/194842_image1_cb987efd-9154-4619-b83f-b94d52e1707b.jpg?v=1787817888","url":"https:\/\/ulegroup.com\/products\/fuse-amp-trap-r-600v-601a-time-delay-class-l-a4by-series","provider":"ULE Group","version":"1.0","type":"link"}
