With a 7 A current rating and a 277 V nominal voltage, this unit is designed to safeguard smaller branch circuits while coordinating effectively within larger distribution systems. Its designation as a Potential Transformer-ready breaker means it’s well-suited for metering and protection setups that rely on accurate voltage sensing and monitoring signals.\u003c\/p\u003e \u003ch2\u003eKey features that set the FAZ-B7\/2-NA apart\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003e2-pole protection\u003c\/strong\u003e — interrupts both live conductors in a 277 V circuit for complete, simultaneous isolation and safer maintenance.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e7 A current rating\u003c\/strong\u003e — precisely tuned to protect smaller control and lighting circuits without nuisance tripping.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e277 V nominal voltage\u003c\/strong\u003e — optimized for commercial\/industrial environments where 277 V distribution is common (such as lighting and certain branch circuits).\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart number clarity\u003c\/strong\u003e — FAZ-B7\/2-NA ensures quick identification and seamless replacement within Eaton-based systems.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePotential Transformer compatibility\u003c\/strong\u003e — designed to support measurement and protection workflows that rely on voltage sensing, enabling smoother integration with monitoring relays and metering equipment.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e dependable Eaton engineering\u003c\/strong\u003e — built to integrate with other Eaton components and panels, delivering consistent performance in daily operations.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eIdeal applications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e277 V lighting circuits in commercial spaces such as offices, retail centers, and warehouses.\u003c\/li\u003e \u003cli\u003eSmall control circuits for HVAC, fans, and vending systems that require reliable overcurrent protection.\u003c\/li\u003e \u003cli\u003ePanelboard configurations where multiple 277 V branches must be isolated quickly and safely.\u003c\/li\u003e \u003cli\u003eProtection schemes that benefit from potential transformer signaling to feed metering or protection relays.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWhy this breaker is the right choice for your panel\u003c\/h2\u003e\n\u003cp\u003eThe FAZ-B7\/2-NA isn’t just a generic breaker. Its 2-pole design ensures you can safely disconnect both conductors in a 277 V circuit, reducing the risk of backfeed and improving maintenance safety. The 7 A rating makes it ideal for protecting mid-sized control circuits and lighting runs without over‑tripping under normal load variations. Plus, its potential transformer compatibility gives you a straightforward path to integrate with modern protection and monitoring systems, lowering wiring complexity and improving diagnostic capabilities.\u003c\/p\u003e \u003cp\u003eStocking the \u003cstrong\u003eEaton FAZ-B7\/2-NA\u003c\/strong\u003e means you’re prepared for reliable protection in 277 V environments, with a unit that aligns with Eaton’s ecosystem and supports future metering and monitoring needs. If you’re upgrading or stocking parts for commercial electrical installs, this 7 A, 2-pole, 277 V breaker offers precise protection, easy replacement, and thoughtful integration features that translate to real-world reliability and peace of mind.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Eaton","offers":[{"title":"Default Title","offer_id":46423235068066,"sku":"FAZ-B7\/2-NA","price":665.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_229276d9-908d-46df-93e5-6fe31866e0ff.png?v=1765492975","url":"https:\/\/www.ampstate.com\/products\/eaton-faz-b7-2-na","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
