The cartridge measures 13\/32 in × 1-1\/2 in (10.3 mm × 38.1 mm) and uses ferrule-end terminations with nickel-plated brass end caps and a fiber-filled tube for durability. Ferrule-end terminations are designed to fit standard fuse holders and panel grids, making installation straightforward in control panels and distribution boxes. This slow-blow device is designed to tolerate brief overloads typical of line protection and transformer inrush, while reliably interrupting current on sustained faults. The melamine tube provides dimensional stability and resistance to heat, contributing to consistent protection in demanding environments. Common applications include line protection and protection of small control transformers and industrial control circuits in electrical panels and branch circuits, where a 4 A rating matches the load. As part of the FNQ Limitron family, the FNQ-4 provides compact, 500 VAC protection for commercial and industrial systems, enabling safe, selective protection in control panels, power distribution, and other low-to-mid-power applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"BUSSMANN","offers":[{"title":"New","offer_id":51677543072046,"sku":null,"price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_edb9f485-b8cc-42c0-a809-3d05ab56de33.jpg?v=1769564398","url":"https:\/\/plgautomation.com\/products\/eaton-bussmann-fnq-4-limitron-time-delay-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
