Its primary function is to automatically interrupt current when a circuit experiences an overload or short circuit, protecting conductors, insulation, and connected devices from damage and reducing the risk of fire or electrical shock. The 480 VAC rating applies to alternating-current distribution, typical of industrial or commercial power systems, while the 125\/250 VDC rating establishes the direct-current limits the device can safely interrupt. As a two-pole model, NEF421020 provides simultaneous disconnection of two conductors, enabling effective protection for multi-wire circuits in panel installations that require coordinated trip behavior.\u003c\/p\u003e\u003c\/div\u003e","brand":"Federal","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51686318702894,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4f763ef6-c45b-43df-8b2a-3d3f076a2a4f.jpg?v=1769737745","url":"https:\/\/plgautomation.com\/products\/federal-pacific-electric-nef421020-2-pole-circuit-breaker-20a-480vac-125-250vdc","provider":"PLG Automation ","version":"1.0","type":"link"}
