It is rated for 400 A with a 150 VAC\/VDC voltage rating, making it suitable for semiconductor protection in high-current DC and AC circuits such as DC buses, power supplies, drives, rectifiers, and other power-conversion assemblies. As a semiconductor fuse, the FWA-400A is designed to respond rapidly to overcurrent events to shield sensitive components while allowing normal operation under safe conditions. This form-factor is consistent with other FWA-series devices and is used where fast clearance of faults is required in motor drives, DC power stages, and solid-state converters. When selecting this fuse, verify that the maximum system voltage does not exceed 150 V and that the current rating provides adequate protection for the expected load and fault conditions, balancing reliable protection with minimizing nuisance blows.\u003c\/p\u003e\u003c\/div\u003e","brand":"Bussmann","offers":[{"title":"New","offer_id":51677535600942,"sku":null,"price":106.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ff736ea8-8190-4509-b2b0-842e26de530a.jpg?v=1769564264","url":"https:\/\/plgautomation.com\/products\/bussmann-by-eaton-fwa-400a-semiconductor-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
