This MCCB provides overcurrent protection for three‑phase feeders and distribution circuits in industrial or commercial power systems, enabling safe isolation of faults and protection of conductors at 480 VAC. The device is associated with Federal Pacific Electric and American Circuit Breaker (FPE\/ACBC) lineage, reflecting its use in legacy installations where NEF‑series MCCBs were specified. When selecting a replacement, verify panel compatibility with NEF series devices and ensure the breaker’s rating and trip characteristics align with your system’s fault current and load profile. The 80 A, 480 V designation identifies its primary application in protecting three‑phase equipment such as motors, conveyors, pumps, and processing lines in commercial and industrial environments, where reliable interruption of fault current helps safeguard conductors and downstream gear. This molded housing formulation supports a compact form factor suitable for retrofits in panels designed for MCCB protection, and the NEF437080 labeling provides a precise reference for sourcing the exact part in catalogs and distributor listings. \u003c\/p\u003e\u003c\/div\u003e","brand":"American","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659906187566,"sku":null,"price":392.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_81141842-199e-4b3a-9e68-99511569b8ff.jpg?v=1769530551","url":"https:\/\/plgautomation.com\/products\/industrial-nef437080-molded-case-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
