This Hubbell device interrupts current on a single conductor in a compatible distribution panel to provide overcurrent protection for an individual circuit. The 400 A rating and 600 V maximum operating voltage establish its use for high-capacity feeders or branch circuits within electrical installations that require robust protection. The HBL400FBK designation helps with accurate specification, cross-referencing, and replacement planning in electrical panels and switchgear. This breaker is suitable for use in electrical installations requiring a single-pole protection solution for high-current circuits. When selecting this breaker, verify compatibility with your panel’s bus configuration, the system voltage, and applicable electrical codes to ensure proper integration and safe operation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Hubbell","offers":[{"title":"New","offer_id":46261809152234,"sku":null,"price":386.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-050.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/hubbell-hbl400fbk-single-pole-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
