Identified by the FWX-400A model number, this device is part of Cooper Bussmann’s lineup of protective fuses designed for high-current electronics. As a semiconductor fuse, its function is to interrupt current when a fault or surge exceeds safe operating levels, helping prevent damage to power supplies, drives, inverters, and other semiconductor-based equipment. With a 400 A rating, the FWX-400A provides a clear specification for selecting protective devices in systems where substantial current needs to be interrupted to safeguard sensitive components. Semiconductor fuses like the FWX-400A are commonly used in power supplies, motor control electronics, inverters, and other high-current semiconductor assemblies to quickly interrupt fault currents and protect downstream circuitry. Designed for use in demanding, high-current environments such as industrial power electronics and energy storage interfaces.\u003c\/p\u003e\u003c\/div\u003e","brand":"Cooper","offers":[{"title":"New","offer_id":51679871172910,"sku":null,"price":41.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b633c689-3725-4b94-96d7-cb165e831d67.jpg?v=1769614705","url":"https:\/\/plgautomation.com\/products\/cooper-bussmann-fwx-400a-semiconductor-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
