This NB320 U model provides protective disconnect for three hot conductors, helping prevent damage from overloads or short circuits and reducing electrical hazards associated with overcurrent conditions. With a 20A rating, normal operating currents should stay below the trip threshold, ensuring continuous service for properly sized branch circuits. The three-pole configuration makes it suitable for 240V applications that require simultaneous disconnection of all three live conductors, such as certain 240V equipment or multi-wire branch circuits. The NB320 U designation identifies the specific Federal Pacific Electric breaker family and rating, enabling technicians to match the device to installations that call for this model. In practice, selecting the NB320 U ensures you have a dedicated protective device for a 240V, three-conductor circuit at the 20-amp level, supporting safe operation and fault isolation in electrical distribution.\u003c\/p\u003e\u003c\/div\u003e","brand":"FPE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51691083170094,"sku":null,"price":276.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a1cb09fd-003a-4b00-9987-36800e493724.jpg?v=1769880051","url":"https:\/\/plgautomation.com\/products\/federal-pacific-electric-nb320-u-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
