As part of Federal Pacific Electric's NB-series family, the NB370U is intended for use in panels and distribution systems that require a 70A, 3P, 240V breaker to protect feeders and motors from overloads and short circuits. With three-pole operation, all conductors disconnect simultaneously to isolate faults and prevent backfeed on the other phases. This rating makes it suitable for medium-current loads commonly found in commercial or light industrial applications that run on 240V three-phase power. Installers should ensure the panel is labeled for NB-series breakers and that the installation complies with local electrical codes and the panel manufacturer's instructions to provide proper overcurrent protection for connected loads.\u003c\/p\u003e\u003c\/div\u003e","brand":"FPE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51691083104558,"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_c622810c-f59b-410c-9877-749f90081455.jpg?v=1769880043","url":"https:\/\/plgautomation.com\/products\/federal-pacific-electric-nb370u-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
