Designed for industrial power-distribution applications, this FA-frame device provides overcurrent protection for feeders and branch circuits in panelboards and switchboards that support FA-series MCCBs. With a compact molded enclosure and standard line and load terminals, it fits compatible Square D installations and aims to simplify replacement in 480-volt systems where reliable protection is required. The 40‑amp rating makes it suitable for protecting moderate-load circuits such as motor feeders, transformers, and other industrial equipment within an FA-series distribution scheme. Use is appropriate in environments where precise 3‑pole protection at 480 VAC is needed to prevent damage from overloads or short circuits, while enabling straightforward manual tripping and restoration after faults. For exact mounting dimensions, terminal sizes, and compatibility notes, consult the official Schneider Electric FA-series catalog or datasheet to ensure a proper fit with your enclosure and bus configuration.\u003c\/p\u003e\u003c\/div\u003e","brand":"SQUARE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259018072298,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/square-d-fa34040-bu-molded-case-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
