This device provides a visible alert when a fuse has opened, helping maintenance staff quickly locate faults in power-distribution panels or machine-control cabinets. The BF1304M U designation identifies the specific indicator type within the BF family, and listings for this part commonly appear in used-condition inventories, reflecting its vintage or legacy status. When properly installed on compatible BF-series equipment, the indicator operates as part of the panel’s fault-detection features, enabling faster response times and improved panel diagnostics in industrial environments. Prospective buyers should verify compatibility with their BF-series breakers and enclosure configurations before purchase, as compatibility can vary across older Square D assemblies and panel designs. This item is typically offered without warranty terms in secondary markets and is seen in surplus or resale channels among electrical distributors and repair shops.\u003c\/p\u003e\u003c\/div\u003e","brand":"SQUARE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46258974064874,"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-bf1304m-u-industrial-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
