It is rated for 600V and 1000A with a high interrupting rating of 200kA, suitable for use in mains feeders, load centers, panelboards, switchboards, and metering centers. This time-delay fuse allows coordination with ground fault relays by passing normal current surges due to its 4-second minimum time delay at 500% rating. It is an essential component for electrical distributors and switchgear suppliers focusing on reliable wire and cable protection and lighting solutions.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eManufacturer: Mersen\u003c\/li\u003e\n  \u003cli\u003eManufacturer Part #: A4BY1000\u003c\/li\u003e\n  \u003cli\u003eVoltage Rating: 600VAC \/ 300VDC\u003c\/li\u003e\n  \u003cli\u003eAmperage Rating: 1000 A\u003c\/li\u003e\n  \u003cli\u003eInterrupting Rating: 200 kA\u003c\/li\u003e\n  \u003cli\u003eFuse Class: Class L\u003c\/li\u003e\n  \u003cli\u003eConnection Type: Blade\u003c\/li\u003e\n  \u003cli\u003eMounting Type: Bolted\u003c\/li\u003e\n  \u003cli\u003eDimensions (L x W x H): 10.75 in x 2.5 in x 2.5 in\u003c\/li\u003e\n  \u003cli\u003eDiameter: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003eProduct Weight: 4.28 lbs\u003c\/li\u003e\n  \u003cli\u003eInsulation Material: GMG (Glass Melamine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e100% rated device for continuous current up to ampere rating\u003c\/li\u003e\n  \u003cli\u003e4-second minimum time-delay at 500% rating for surge tolerance\u003c\/li\u003e\n  \u003cli\u003eCurrent-limiting design to protect electrical systems\u003c\/li\u003e\n  \u003cli\u003eUnique dimensions prevent replacement by other fuse classes\u003c\/li\u003e\n  \u003cli\u003eBlade stamped catalog numbers for permanent identification\u003c\/li\u003e\n  \u003cli\u003eGlass melamine body and plated terminals for superior reliability in harsh environments\u003c\/li\u003e\n  \u003cli\u003eUL listed to standard 248-10 and CSA certified\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=403450\" 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=403450\" 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=403450\" 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\/d4c1d505d50b00867766fc5012ee3f52df1cc999.pdf?did=4169\u0026amp;pid=403450\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDrawings\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/mersen\/2021q1\/documents\/1a2f877f363cb973a53a58e7151167469ddba921.pdf?did=4169\u0026amp;pid=403450\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCurves 2\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mersen","offers":[{"title":"Default Title","offer_id":46093212221665,"sku":"194700","price":585.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/9625\/4433\/files\/194700_image1_1b6f273e-75d1-4175-89a3-ceae265aec99.jpg?v=1787829377","url":"https:\/\/ulegroup.com\/products\/fuse-amp-trap-r-600v-1000a-time-delay-class-l-a4by-series","provider":"ULE Group","version":"1.0","type":"link"}
