With a 3‑ampere rating and a 50\/60 Hz operating frequency, this FAZ-D3 MCB is suited for electrical installations that require reliable, compact protection for a single energized conductor. As part of Eaton's NSB FAZ series, it is intended for use in panelboards or distribution blocks that accept 1P protection blocks. The 277 V rating aligns with applications where equipment and lighting runs are supplied from a 277V distribution system, enabling the breaker to quickly interrupt fault currents and help prevent damage to conductors and connected devices. By selecting a 1P 3A device, installers specify protection on a single hot line while preserving the rest of the circuit’s continuity, aligning with standard single-pole protection practices in appropriate voltage environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Eaton","offers":[{"title":"New","offer_id":51685276385582,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8550a995-fa45-4bc3-a3f2-e12ae4d9f002.jpg?v=1769717099","url":"https:\/\/plgautomation.com\/products\/eaton-nsb-faz-d3-1-na-sp-miniature-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
