The device carries an 18 kA short‑circuit interrupting rating at 480 V, supporting reliable fault protection for feeders and motors under high‑fault conditions. Built in ABB's ESB molded‑case family, the ESB43080L U uses a standard three‑phase configuration that fits panelboards and switchgear where space is constrained, and is compatible with common mounting frames and accessories designed for ESB series breakers. In normal operation, it interrupts current when overload or short‑circuit conditions occur, helping to safeguard conductors and equipment downstream. Application areas include motor feeders, machine control panels, distribution panels, and other three‑phase load centers in industrial facilities. When selecting this model, ensure the application requires 480 VAC service, an 80 A protective setting, and an interrupting capacity of 18 kA, and confirm compatibility with your enclosure and mounting rails.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46252469616874,"sku":null,"price":222.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-084.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/abb-esb43080l-u-three-phase-molded-case-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
