This model is rated for 100 A and carries an 18 kA interrupting capacity, enabling it to safely interrupt fault currents to protect downstream conductors and equipment. As part of ABB’s ESB molded-case family, the ESB43100L U provides robust overcurrent protection in low‑voltage distribution systems where a 100 A device is appropriate and space within the panel is at a premium. The device’s 3‑pole configuration aligns with standard three‑phase power arrangements, delivering reliable isolation and protection for circuits powered from a 480 V three‑phase supply. In practice, this MCCB serves as a compact, dependable protective device within electrical panels and switchboards, balancing clear interrupting performance with straightforward installation. ABB’s ESB line is known for dependable protection in industrial and commercial applications, and the ESB43100L U continues this tradition by offering straightforward protection for circuits at the 100 A level with a 480 V rating while maintaining compatibility with ABB’s broader family of molded‑case breakers.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46252469682410,"sku":null,"price":289.0,"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-esb43100l-u-molded-case-circuit-breaker-mccb","provider":"GTG Hardware","version":"1.0","type":"link"}
