Square D EDB24080SA is a molded case circuit breaker designed for overcurrent protection in industrial and commercial power distribution systems. This 80A, 2-pole unit operates at 480Y/277V with a 18kA interrupting capacity at 480V, providing long-time and instantaneous (LI) protection through its thermal magnetic trip mechanism. The bolt-on breaker measures 5.66 in (143.76 mm) x 2.94 in (74.68 mm) x 4.05 in (102.87 mm) and weighs 3.17 lb, featuring lug terminal connections and a 120V shunt trip for remote tripping capability. It is certified to cULus and IEC standards, with a temperature rating of 104°F (40°C), making it suitable for single-phase applications in panelboards and switchboards requiring reliable branch circuit protection.
